Daylighting in Buildings: Sustainable Design Strategies for Building Floorplates
Buildings — including material production, construction, operation, and maintenance — are responsible for more than 55% of global energy use, way more than transportation, industrial and agricultural production combined. To achieve a sustainable balance between the built and natural environments and guarantee healthy and productive lives for future generations, we must rethink the way we design and construct buildings in order to minimize their energy use. Daylighting is one of the fundamental green design strategies, which has direct implications for work productivity, wellbeing, and safety. Architects strive to increase the levels of daylighting in houses, workplaces, educational buildings, and healthcare facilities either by increasing the amount of fenestration or by limiting the depth of floorplates so that most spaces in buildings are close to the daylight perimeter. Meanwhile, daylight buildings not only make for happier and healthier tenants, but they also require less energy for artificial lighting. But there is a catch, which comes bundled in three main issues: First, the more we elongate buildings to minimize floorplate depth, the longer the length of the building envelope thus the total construction cost; Second, due to longer envelopes, skinny buildings are more prone to energy loss through their perimeters and thus require more energy for cooling and heating; Third, in most climatic zones, buildings with elongated floorplates could be prone to overheating due to direct sunlight when shading is not considered well.
The project seeks to raise students’ understanding about the effect of basic building design on daylight levels, energy use, as related to sustainable design goals. Students will analyze a large stock of buildings in KSU campuses and the surrounding areas of Cobb County focusing on the shape and size of building floorplates. Relying on simple measurements of daylight levels, and the well-established precedent normative indices, students will develop a classificatory matrix that brings together building area, envelope area, and daylight levels as a derivative of the building floorplate shape. The classification matrix would enable the rating of various buildings form the standpoint of the optimal balance between high levels of daylighting and low envelope cost.

Impact of Air Pollution Exposure in Latino Communities: An Equity-based Framework
for Environmental Engineering
What makes a community sustainable, equitable, and healthy to serve people of different backgrounds, resources, and abilities? What is the impact of the built environment
on human health, safety, and welfare at multiple scales, from buildings to cities?
This research instills in students a holistic understanding of Sustainable Development Goals and the role of the design process in integrating multiple factors to shape the built environment on different scales. Our projects aim to deepen understanding of diversocioctors (such as socio-cultural) that impact sustainability, equity, and health in a community. The projects challenge students to solve complex problems through effective collaboration skills, emerging sustainable systems, and innovative design strategies. Students would be engaged in design research projects advocating the integration of multiple factors in shaping healthy environments — framed by diverse ecological, social, cultural, political, and economic forces.

of efficient algorithms on energy-starved IoE application networking systems, (2)
array antenna control systems to determine beamforming for data transmission reliability
and energy efficiency, and (3) a new cloud network paradigm such as a consolidation
of Low-Power Wide-Area Network (LPWAN) such as using Long Range Radio (LoRa) technology
with edge cloud computing to support QoS both energy-starved IoE and general Internet-of-Thinks
(IoT) data communications. LoRa is a low energy consumption, low bit rate, cost-effective,
and license-free IoT, which has a significant long range. LoRa can be combined with
software-defined networking to create unified, adaptable, rapid-deployable networks.
Therefore, these project solutions are applicable to many high-impact situations where
communication is lost, as well as monitoring energy intake and usage patterns at the
data-driven application site, zone, system, and device level.

Addressing Challenges of Cybersecurity Education and Research
There has been an increasing effort in cybersecurity teacher preparation for secondary education in recent years. However, one of the significant challenges teachers face when trying to teach cybersecurity topics is the lack of expertise, time, and resources needed to develop a cybersecurity curriculum for their classrooms. With this need in mind, the goal of this project is to develop a standards-based cybersecurity curriculum for secondary education to help increase student cybersecurity literacy and build a robust pipeline of future cybersecurity talents. The expected outcome of this project is to provide a comprehensive, ready-to-use, standards-based, hands-on cybersecurity curriculum that is readily available for secondary education teachers to implement in their classrooms. This project will also develop a website that shows the research contents, research team publications, and researchers’ names.

Website Fingerprinting: Attacks and Defenses
Website fingerprinting acts as a detective trying to guess what one has been up to online. Imagine someone looking at the digital 'footprints' left by web browsing - the timing, direction, and size of the data sent and received, even if tools are used to keep online activities private, like proxies, VPNs, or Tor, this detective could potentially piece together which websites have been visited. In this field, machine learning (a smart computer program that can learn from patterns) is used to better understand and protect online privacy. In the case of website fingerprinting, these smart programs can analyze data footprints and guess the websites they originally came from. This project revolves around investigating methods to safeguard digital privacy and comprehending the strategies employed to compromise it, specifically in the domain of web security. The application of web security techniques is at the core of this study, aiming to enhance the protection of users’ online activities and data from prying eyes. By delving into the intricacies of website fingerprinting and employing machine learning methodologies, the project seeks to contribute to a more secure and privacy-conscious digital landscape.

The Role of Phosphorus-Containing Minerals in the Origin of Life
Phosphorus is one of the six essential elements for life, playing a key role in our
nucleic acids (DNA, RNA), cell membranes (bilayersipid bilayers), and coenzymes (e.g.,
ATP). Discovering the mechanisms by which phosphorus is released from minerals and
characterizing the subsequent reactivity is crucial to understanding the origin of
life on Earth and the potential for life to exist elsewhere in our universe. In this
project, students will monitor the chemistry of phosphorus-containing minerals with
water and small organic molecules to determine what abiotic or non-biological reactions
occur.
Following synthesis, which Ellie has already successfully learned phosphitetal phosphite samples will be analyzed using infrared spectroscopy, x-ray diffraction, and NMR or nuclear magnetic resonance to confirm their structure. Additionally, careful measurements on the solubility pHsdifferent pHs will be performed. Following characterization, students will perform reactions betwephosphitesal phosphitesprebioticand prebiotic molecules such propanolnol, propanol and glyphosphitetal phosphite samples will be reacted at modest temperatures (60-80oC) and atmospheric pressure, approximating the conditions in tidal pools on the early Earth. The formation and relative abundances of organic molecules containing phosphorusphosphonates phosphonates and organophosphates, will be identified using NMR.
The proposed experiments will address the research question, “What products can be formed when phosphorus-bearing mineabioticallyd abiotically with prebiotic molecules in comets or on the early Earth?” The information obtained during this project will origin-of-life scientists determphosphitesal phosphites could have been an important precursor for phosphorubiomolecules biomolecules on the early Earth.

Mechanism of Transcription Regulation by Metalloregulators
Our laboratory uses various molecular biology and biophysical techniques to determine
consensus DNA-binding sequences for transcription factor proteins. Transcription factors
are essential regulators in all organisms that control gene expression. In bacteria,
transcription factors often regulate genes by binding to a specific DNA sequence usually
found immediately upstream of the regulated gene, and DNA-bound transcription factors
either enhance or repress the ability of RNA polymerase to initiate transcription.
Typically, transcription factors respond to environmental stimuli, often requiring
a co-factor to bind DNA efficiently.
For this project, we are interested in determining the transcription regulatory network (i.e. the set of genes a transcription factor regulates) for a DtxR family regulator in the model bacterium, Thermus thermophilus HB8. DtxR regulators are found extensively throughout gram-positive and gram-negative bacteria, and these transcription factors often regulate genes involved in heavy metal transport. Additionally, DtxR proteins often require a metal cofactor to bind DNA. Notably, Thermus thermophilus has only one DtxR homolog (encoded by the TTHA0754 gene), and no previous literature exists regarding this protein.

A Major Regulator of Germline Transcription, LSL-1, Contributes to Developmental Defects
when Histone Methylation is Inappropriately Inherited
Histone methylation is a post-transcriptional modification to the N-terminal tails
of histone core proteins that regulates DNA accessibility, and consequently, gene
expression. Like DNA, histone methylation can be inherited between generations, and
is highly regulated during embryonic development. At fertilization, histone methylation
must undergo maternal reprogramming to reset the epigenetic landscape in the new zygote.
During maternal reprogramming of histone methylation in the nematode, C. elegans,
H3K4me (a modification associated with active transcription) is removed by the H3K4
demethylase, SPR-5, and H3K9me (a modification associated with transcriptional repression)
is subsequently added by the histone methyltransferase, MET-2. Maternal loss of SPR-5
and MET-2 results in ectopic expression of germline genes in somatic tissues and a
range of developmental phenotypes, including a severe developmental delay. Using a
combination of RNA-seq and ChIP-seq experiments, a recent study identified a major
regulator of germline transcription, LSL-1, that turns on germline genes in the germline
during development. From our own transcriptional analysis performed on C. elegans
lacking SPR-5 and MET-2, we find that lsl-1 is significantly upregulated in somatic
tissues. Together these data suggest that LSL-1 may be turning on germline genes aberrantly
in somatic tissue and contributing to developmental delay. To test this hypothesis,
we knocked down lsl-1 using RNA interference (RNAi) and found that the developmental
delay in spr-5; met-2 mutants is significantly rescued.
To take the next steps in this exciting project as a sophomore, we will perform RNA-seq to identify the germline genes in spr-5; met-2 mutants that are dependent on LSL-1 and that contribute to complex developmental phenotypes including developmental delay. In addition, we will perform follow up genetic and immunohistochemistry experiments to complete the data necessary to begin writing a manuscript. Together, our findings will provide mechanistic insight into how inappropriate inheritance of epigenetic states perturb germline versus somatic cell fate specification during embryonic development.

Investigating the Impact of Prescribed Burns on the SoMicrobiomeal Microbiome of the
Longleaf Pine
In our lab, we are investigating different aspects of the longleaf pine ecosystem, which is an ecosystem that used to cover about 90 million acres across the Southern US but has been reduced to less than 3% of its original range. Because it is home to more than 30 endangered and threatened species, as well as due to the value of the longleaf pine trees themselves, the restoration of this ecosystem has become a strong priority.
The longleaf pine ecosystem relies on frequent fires to subsist, and its range has been reduced in part because of fire suppression, but clearing the forests for construction, development, agriculture, and faster growing species for lumber have also played a role. For his sophomore scholar’s year Dylan would like to focus his research on an aspect of our broader study. Dylan would like to follow up with a self-contained project and study the ecological succession of the bacterial soil community at our study site after fire.
Over the first year some of the 1st. Year Scholars in our team were fortunate to observe a prescribed, controlled burn at our study site; implemented as part of the restoration initiatives for the longleaf pine ecosystem. We took advantage of this burn and collected soil samples shortly thereafter and at increasing time intervals. Little is known about the microbiome of the soil of the Montane Longleaf Pine, and less about the ecological succession that takes place shortly after fire. The longleaf pine ecosystem is frequently subdivided into four different habitat types: Montane, Sandhills, Rolling Hills and Flatwoods. The least known of these is the Montane habitat, which is where our study site is located.
We think that that by characterizing the soil microbiome (getting to know the community of organisms in the soil) in general, and in particular, given that fire is such an integral part of the restoration process, studying the ecological succession within the soil community after a fire, we will be able to help inform the restoration of this ecosystem. Dylan’s work on this project will greatly help move this aim forward.

What’s in a Fish? A Survey of Parasites Infecting Freshwater Fish Species in Georgia
Georgia is a hotspot for freshwater fish diversity in the United States, yet we know almost nothing about the parasites infecting these species. With my research program, I seek to survey and describe the parasitic diseases of freshwater fish in the state. I am requesting funds for Kaleigh Jones to assist in this research. KSU has 188 jars containing almost 1000 ethanol-preserved freshwater fish collected around the state between 1999 and 2016; 115 species of fish are represented in this collection! Kaleigh will continue her work with these specimens, dissecting these fish using a stereo microscope and collecting and identifying their parasites using a compound microscope. She will collect data on the host and parasites on paper datasheets and then will input the data into a shared datasheet on OneDrive at the end of the week. We will use these data to publish surveys on parasitic diseases of these fish species and study the distribution of diseases across Georgia watersheds. Kaleigh will also use the data she collects to continue her work on an independent research project. Last year, Kaleigh investigated the parasite fauna of two families of freshwater fish in Georgia, Ictaluridae and Catostomidae, with another undergraduate researcher. She will continue on this project, adding in additional taxa when needed.

The Effects of Personality on Post-Traumatic Growth
Last year, KSU students and I expanded on previous research by evaluating models of resilience among individuals with above-threshold PTSD symptomology. Our goal was to validate a model for theoretical anxiety buffers anticipated to mitigate the harmful impacts of traumatic experiences. This research enriched the wider literature and solidified the theoretical foundations of ABDT. Moreover, it paved the way for exploring interventions that harness individuals’ innate resources and the cultural foundations underpinning them. Our student team showcased this work at both local and national conferences, and we have been diligently preparing for publication. In this context, Alexa's previous contributions stand out. In prior semesters, Alexa introduced innovative approaches to evaluate factors she believed would moderate the relationship between anxiety buffers aimed at lessening the psychological aftermath of traumatic events on long-term outcomes. Inspired by prior research, Alexa emphasized evaluating the role of personality at the individual level and pinpointing its role as a pivotal moderator overall model. This year, we will be focused on expanding this research through a true experiment. Our design will evaluate whether mere contemplation of death can trigger comparable reactions (though considerably milder in intensity) and then evaluate whether or not elements of personality serve to counteract the existential anxiety stemming from the manipulation.

Social Support, Identity, and Aspirations of Opportunity Youth
During the Fall semester, the sophomore-year scholar will focus on recruiting and interviewing youth who are not currently in school or work, commonly referred to as “disconnected youth” or “opportunity youth,” about their experiences, connectedness, and aspirations. During the Spring semester, the sophomore-year scholar will have the opportunity to work on transcription, coding, and analysis of the interview data just described.
This project extends the work conducted during the first-year scholars experience, which focused on conducting reviews of prior research and using those reviews to design and plan for the qualitative study explained above. This project will involve collaborating with other students to recruit and interview 30 youth. The sophomore-year scholar will also be supported to pursue research questions they are passionate about from this or other studies undertaken by our research group, which will set the stage for research capstone or other research-oriented experiences during the student’s junior and senior years.

Modeling and Analysis of Silting in a Local Lake in Kennesaw, GA.
The proposed research builds upon the work completed with the support of the First Year Scholars Program. It included field surveys of Frey Lake using different equipment including a laser scanner and a drone. We also collected a significant amount of historical data on the landscape as well as long-term climate data. The requested funds from the Sophomore Scholars Program will be used to add a new layer of surveys to model the silt thickness and silt distribution in Frey Lake. It will involve using an inflatable boat, depth sounder, and sonar. The data will be used for geospatial modeling and preparing raster as well as vector models of the distribution of silt thickness across the lake bed. The objective is to use these results and write a manuscript for a peer reviewed journal such as Geographical Bulletin. The proposed research will increase our understanding of freshwater lakes which serve
multiple function for cities across the world such as providing water to communities,
controlling floods by storing extra water, offering recreational opportunities, promoting
fish and wildlife, and serving as natural laboratories for ecological research. While
providing cutting-edge training to the student, it would also support the efforts
of many local, regional, and state agencies involved in the management of freshwater
systems.

Voices of Resilience: Women in Law Enforcement Navigating Communication Barriers
The project is a continuation of last years’ project examining law enforcement narratives. It would provide clarification and contradictions necessary to understand the layers of communicating in a masculine profession. A masculine profession is one that has historically been held by men. In addition, the rules, norms, and culture of the profession are rooted in masculine values (i.e., competition, aggression, and power etc.). Women face unique communication challenges in the workplace. Then, within various professions, the differences can vary. Law enforcement presents a complex communication environment Emma Smalley found as a FYS, interviewed women in various states regarding mentorship, assimilation, and experiences of isolation. She transcribed and coded interviews. The results led to several other explorations such as, men’s perspective, representation within social media, retention, and motherhood.

Compounded Grief Beyond the Pandemic: What it Looks Like and How People Cope
Many families rarely talk about death, grief, and end of life before one our loved ones are going through it. Even then, the topic is so taboo in the United States, that many continue to avoid conversations surrounding death or grief altogether. But research has shown us that when parents talk to their children about major, often taboo, issues such as sex, alcohol, or drugs, kids are likely to engage in healthier habits overall. These kids are also more likely to talk to others about these issues (like romantic partners or friends when it comes up) and to feel like they can go to their parents if they need to about these types of topics. So why would the same not be the case when it comes to death? That is, if we talk to our loved ones about death in some way (relationships, laughing, storytelling, love, religion, final wishes, identity), would their children be better able to have conversations with their own families, talk about their grief with others (including therapists), and better able to cope overall? That is what we are hoping to find out. And along the way, we hope to destigmatize death and grief, especially during a time in our society, when it seems to surround us.
This year, we will be diving headfirst into the Quantitative data we collected (which took almost 4mos to collect 280 quality responses). With Kelly and Jessica, Ella and I will be exploring a number of end-of- life issues, including grief, final conversations, and communal coping and coping strategies. We aim to get at least 2 manuscripts out of this data set this year, with another the following year.
Ella also aims to take the feedback she received from NCUR and the student symposium to improve her manuscript that work with some of the qualitative data from a portion of that dataset. From there, we will look at getting that manuscript published this year.
With Dr. Elue, we are looking at grief in the eyes of students. She and I are working on how people turned to the internet to grieve right now, by analyzing themes on Reddit. We will be publishing this piece over the summer. We then are looking forward to doing a similar project using SAS analysis (working with Dr. Gary Wilcox) to examine students specifically and their return to college, coping with the pandemic, being overwhelmed following the pandemic, and dealing with various issues of grief at that time. We are also developing a roadmap to interview or conduct focus groups to explore nontraditional students, veteran students, first generational students, and/or international students and their experiences of various forms of grief and compounded grief in college, including how they cope with it.

Autonomous Robotic Navigation in Complex Terrains
Making a vehicle drive itself off-road is quite different from self-driving cars on
regular roads. Off-road situations lack clear rules and lanes, which means the vehicle
must handle unexpected challenges as they come up. Industries like Agriculture, Construction,
Mining, and Space Exploration are interested in using automation for tasks usually
done by people, especially those that are boring or even dangerous. Automating off-road
vehicles does not just help with tasks; it brings a bunch of benefits. It lets industries
grow their work easily. These automated vehicles can work in lots of places without
much trouble. This kind of flexibility makes work faster and more efficient.
Additionally, using automated vehicles means work does not have to stop. They do not
get tired or need breaks, so they can keep going without pauses. This helps get tasks
done sooner and makes things work better overall.
In this project, the student will create a self-driving robot by combining basic programming skills and robotics components. The student will start with a small robot kit, like Arduino or Raspberry Pi, and learn programming languages like Python or C++. The student will attach sensors such as ultrasonic or infrared to help the robot "see" its surroundings. This allows to write code that processes sensor data to make decisions, like avoiding obstacles. The work gradually improves robot's capabilities by adding more sensors and refining the code. Online tutorials, forums, and libraries are great resources. Through experimentation, learning, and iteration, the student will gain valuable skills in robotics, coding, and problem-solving while bringing a self-driving robot to life.

The Effect of Gaming on Novice Pilots
Global aviation is suffering pilot shortage; by 2032, it is expected that international
aviation will be 80,000 pilots short. Hence, there is an immediate need to identify
ways to expedite pilot training. Researchers have found that gaming positively impacts
cognition and hand coordination. Specifically, the abilities of people with expertise
levels in video gaming have significantly affected performance scores in many flight
simulators. However, these studies lack generalization due to the small sample size.
This study investigates whether prior gaming experience impacts the flight performance
of novice pilots using a large sample size, flight simulator, and eye-tracking metrics.
We will gather data on two student groups for this study: students with little or no prior experience with gaming and with significant gaming experience. Both groups will receive initial training on basic operations and controls of an aircraft using KSU’s FAA approved flight simulator. After the initial training, students will be asked to fly a straight and level mission (maintaining a consistent altitude, heading, and attitude). During this task, participants will wear eye-tracking glasses to record what controls their eyes were attending to. They will also be graded based on a rubric. Student researchers will take part in data collection and get hands on experience with participants and data acquisition in addition to basic research skills.
This project is the first of its kind at KSU to use gaze tracking device and a flight simulator, so the results from this research will not only determine whether there are statistically significant differences in how the two groups learn to fly the aircraft but also set a precedent for gaze tracking in aviation research at KSU.

An Analytical Model to Quickly Estimate Battery Capacity and Predict the Remaining
Useful Life of Lithium-Ion Batteries
The research on next-generation energy storage devices become a very important topic due to the increasing demand for high performance and reliable energy storage systems (e.g., Li-ion battery) in the fields of electric vehicles, biocompatible medical devices, and consumer electronics. Lots of efforts are being made in the field of developing innovative materials and improving device fabrication methods so that the device performance can be significantly improved. One of the biggest challenges is to quickly test the device performance to evaluate the changes being made to the design. However, the current battery testing method can take up to months to finish, which significantly slows down the development. It is therefore urgent and necessary to improve the current battery testing methodology to meet the needs of fast development in the market for electric vehicles.
The project proposed a way to enable quick testing through data-driven machine learning prediction and experimental validation. Firstly, a large amount of data will be collected to build the machine learning model through some basic data science skills. Secondly, the physical model will be introduced to improve the accuracy of the model. Finally, the model predicted results will be validated by experimental data, which in turn will also be used to improve the model.
The goal of the first phase of the model is to improve prediction accuracy to >95%. During the second phase of model development, the goal is to reduce testing time to < 24 hours. During the third phase of model development, the goal is to improve prediction accuracy to >99% and to reduce testing time to < 12 hours. Upon the completion of the one-year FYSP program, the goals for all phases have been completed, and a model has been developed for LCO chemistry-based coin cell batteries. We aim to explore a variety of batteries with diverse chemistries and significantly higher energy densities as part of the sophomore program. Our objective is to gather more comprehensive insights applicable to practical electric vehicles. We will apply similar testing procedures to these batteries to identify models capable of effectively simulating battery performance. These models will enable swift predictions and estimations of battery behavior.

Study on Biomimetic Locomotion of a Hexapod Robot Based on Fire Ants Gair Motion
Hexapod robots have been highlighted in the last few decades because of their stable
locomotion in complex and uneven terrain. Multiple legs are controlled with a degree
of insect autonomy so that the robot can move in an uneven and complex environment
to complete a planned task. A Hexapod robot has advanced features such as accessibility
and stability in an extraterrestrial environment.
Biomimicry is one of the most innovative methods to create a solution by mimicking the phenomena in nature. Insects can flexibly alter their gaiting pattern to adapt to various locomotor conditions. Various six-legged insects such as an ant and cockroach have been used as a model for biomimetic robots because legged animals can easily outperform the robots over rough ground.
In this project, we plan to develop a hexapod robot, which creates biomimetic locomotions from gaiting patterns found in a fire ant. To achieve this goal, we formulate the following research objectives: (1) design and fabricate a hexapod robot using 24 degrees of freedom based on an insect, (2) study a gaiting pattern by characterizing locomotions in a fire ant, and (3) develop a control method of a hexapod robot based on the characterized locomotion. The recent development in our lab demonstrated the omnidirectional locomotion tracking system for a walking insect in real time. We will utilize this system to observe the ant's walking behavior, and design various gait patterns (e.g., tripod, tetrapod gait pattern)based on observation. The machine learning-based image processing algorithm (deepLabCut) will be utilized for analyzing a gait pattern. Eventually, we will test the biomimetic locomotion for the developed hexapod robot in various ground conditions.
In the future, this work will be extended to study an adapted gait pattern for a damaged
hexapod robot because a robot cannot be fully operating when one or more legs are
not fully functional during the operations such as rescue and search operations, disaster
responses, and human-inaccessible environments such as distant planet

Design, Development, Modeling, and Validation of Soft Robots in MATLAB Simscape
Soft robots, often inspired by biological structures and living things, are designed, and developed from flexible and deformable materials, unlike traditionally designed rigid mechanisms. Soft robots have the potential to be used in various applications due to their unique characteristics. They can be designed to mimic the movement and behavior of natural organisms, making them suitable for tasks such as delicate object manipulation, exploration of complex and constrained environments, medical procedures, and even assistance in rehabilitation processes. The flexibility and compliance of soft robots also make them safer for interactions with humans and unpredictable surroundings, as they are less likely to cause harm or damage. The advancements within the realm of soft robotics have provided us with insights into a diverse range of potential applications. These applications encompass various domains such as manipulation, locomotion, surgery, animation, and rehabilitation. New studies have also brought up interesting problems about how to understand and control soft robots and materials. Solving these problems is really important for making safe and effective robots that can work well in changing situations.
Despite the numerous advantages of soft robots due to their inherent properties, the challenges arise as the complexity of design increases, such as the derivation of mathematical modeling, optimization of the geometry, and development methods. Creating accurate mathematical models for these robots includes the study of nonlinear and large deformations when the robot interacts under different conditions. Unlike traditional rigid robots, where the design parameters are often more straightforward to define, since soft robots deform during motion, optimizing the design to achieve specific tasks while accounting for their deformable nature is challenging.
To address this problem, we will design, develop, model, optimize, and study the motion analysis of complex soft robots in MATLAB Simscape. Simscape is a toolbox in MATLAB that consists of a library to design and simulate mechanical and electromechanical systems. The toolbox allows the user to design complex rigid, compliant, and soft mechanisms while animating the motion in the mechanics explorer.

Investigating the Social Determinates of Health from a Complex Systems Perspective:
Poverty, Stress, and Human Health in International Context
I have several ongoing projects on which the contributions of a Sophomore Scholar
could be significant. These include my role as co-investigator on an NIH R01 studying
mental health among young women in Kampala, Uganda (where I lead the implementation
evaluation), my ongoing community-engaged research on homelessness as a social determinant
of health, or my theoretical (soon to be empirical) investigation of moral distress
in the child welfare workforce. One of the unique value propositions that I provide
for scholars as a mentor is that there is a wide range of opportunities for them to
engage with, and they are able to make choices throughout the year regarding which
tasks and projects are most suited to their long term academic and professional interests.

Investigating the Social Determinates of Health from a Complex Systems Perspective:
Poverty, Stress, and Human Health in International Context
I have several ongoing projects on which the contributions of a Sophomore Scholar
could be significant. These include my role as co-investigator on an NIH R01 studying
mental health among young women in Kampala, Uganda (where I lead the implementation
evaluation), my ongoing community-engaged research on homelessness as a social determinant
of health, or my theoretical (soon to be empirical) investigation of moral distress
in the child welfare workforce. One of the unique value propositions that I provide
for scholars as a mentor is that there is a wide range of opportunities for them to
engage with, and they are able to make choices throughout the year regarding which
tasks and projects are most suited to their long term academic and professional interests.

Understanding the Needs of Georgia’s Hispanic/Latino Population with Regard to Adolescent Health
Across the United States, young people are at risk for unintended pregnancy and sexually transmitted infections, including HIV. In Georgia, the teen pregnancy rate is ranked the 12th highest in the United States. The rate of HIV diagnoses among young people ages 13 to 24 is more than double the national rate for this age group. Georgia also has some of the highest rates of sexually transmitted infections among young people compared to the rest of the United States. KSU is working with the Georgia Department of Public Health (DPH) to research and evaluate their adolescent health and youth development program and services. State-funded adolescent health and youth development programs and services are available at no cost throughout the state at participating local health departments. These programs are based on the positive youth development approach as recommended by the CDC. It utilizes and recognizes young people’s strengths and promotes positive outcomes for young people by providing opportunities encouraging positive relationships and providing the support needed to build on their strengths. DPH forms critical relationships between district and county health departments as well as after school programs and county and community agencies, holding workshops with parents, faith-based institutions, and public health leaders to foster collaborations around key adolescent health and youth development issues. These programs require the implementation of evidence-based risk reduction strategies addressing HIV/AIDs prevention and teen pregnancy prevention including skill building around communication, goal setting, decision making, and avoiding risky behaviors in order to foster building healthy behaviors, developing life stills and promoting positive youth development. The purpose of this specific project is to work with DPH to collect and analyze data from throughout the state to assess the effectiveness of their adolescent health programs and services and develop recommendations for improvements and next steps. This is a very interdisciplinary research project, and students across all majors are encouraged to apply, particularly those interested in medicine, public health, health education, adolescent/school health, youth development, behavioral health, health equity, health policy, reproductive/sexual health, program evaluation, social science research, quantitative research and statistics, qualitative research, etc.

Sustainable Building Materials: Architectural Forms and Structural Design (History
and Technique in Reinforce Concrete Formworks: A Study of Pier Luigi Nervi Approach)
The last hundred years in architecture and civil engineering have been widely dominated
by the use of concrete, which became the second most consumed commodity after water.
Although concrete and cementitious materials have a low embodied energy (of approximately
MJ90 MJ/kg), they are used in vast quantities. In 2016 world production of cement
amounted to approximately 2.8 billion tons, with production and usage accounting for
almost 8-9% of total global anthropogenic greenhouse gas emissions.
Although the technology has improved, providing stronger and more durable concrete,
the construction techniques have not changed. Historically, concrete and reinforced
concrete structures have been constructed using rigid formwork, mainly relying on
the use of either steel or timber to generate the required temporary support structure.
Starting from these considerations, this research project aims to advance our fundamental
understanding of nonrigid concrete formworks in an effort to marry architectural form
and structural design. By challenging the paradigm of rigid formwork, this research
technology will impact the embodied energy and the carbon emission associated with
new concrete constructions by possibly saving up to 30% in concrete volume when compared
to an equivalent strength prismatic member. In addition, the provision of an inexpensive,
extremely lightweight, and globally available formwork material in place of wood will
help address the need for housing in building economies that rely on reinforced concrete
construction but lack in access of wood construction materials. This research thus
offers exciting opportunities for engineers and architects in the move towards a more
sustainable construction industry.
Students working on this research project will investigate the use of formwork in
concrete structures with varying degree of flexibility to achieve:
- more economical construction while improving sustainability and resilience of concrete
structures
- conform to varying architectural forms
- the adoption of advanced concrete materials (such as Ultra High Performance Concrete,
Engineered Cementitious Composites, etc.) in constructions

Study of the Impact of Skin Properties in ML for Glucose Estimation
Accurate understating of the absorption (scattering) properties of human skin is still
a challenge in biomedical optics and biomedical engineering. Furthermore, the impact
of skin roughness and pigmentation is known to affect the light distribution when
light beams are propagating through the skin. In this project, estimating the impact
of these factors on the images obtained from fingers, ears,and other tissues is crucial
for determining features that make the ML model more accurate. In this regard, the
student will work with Dr. Valero and Dr. Lu from East Carolina University, whose
primary research has been based on the understanding of biological systems by investigating
their interaction with light by the measurement of scattered light signals. The project
will follow an approach based on the study of Radiative Transfer Theory, the two-layer
model human skin, and the influence of angles in light scattering.
The first parameter that we are interested in studying and incorporating in the ML
model for glucose monitoring is the light propagation within the tissue. Because we
are interested in understating the light propagation on a survey of cylindrical tissue
(finger or earlobe), we will express the fluence on the edge of a circle and obtain
the scattering profile at a cross-section with radius 𝑎 . We will incorporate the
features of light propagation and study the impact in our current ML model. Studies
will be conducted to determine light propagation and absorption in other tissues like
ear lobulescruracrura of antihelix. The second parameter that will be studied is the
skin roughness impact on the blood glucose model. To understand the implications,
we will use the two-layer model human-skin proposed by Dr. Lu. We will use it to determine
the impact of the roughness on light absorption and investigate if the variables introduced
by roughness can be used as features for AI model. The third parameter that will be
considered is skin pigmentation. The natural absorbers present in tissue are the chromophores
that are present in biological pigments, specifically, the heme pigment of hemoglobin,
myoglobin, bilirubin, and melanin. Melanin is one of the critical contributors to
skin pigmentation. We will perform a quantitative approach to systematically measure
the absorption of different wavelength lasers in our current prototype, the impact
of the model results, to finally select a light laser with a wavelength in a range
acceptable (producing accurate glucose ) for different levels of melanin.

Towards Bounding the Behavior of Deep Neural Networks
Advances in Artificial Intelligence (AI), particularly in the form of deep neural
networks, have revolutionized a diverse range of fields. As neural networks become
more pervasive, the need to understand the boundaries of their behavior is becoming
increasingly important. For example, can we formally guarantee that an autonomous
vehicle will not violate traffic laws, such as reaching excessive speeds? Towards
the goal of bounding the behavior of a neural network, we propose first to bound the
behavior of individual neurons by incrementally tightening formal bounds on it. Subsequently,
we seek to bound the behavior of a neural network.

Design of a Soft Hand Prosthesis with Deep Learning Vision-based Manipulation for
Disabled People
Over 2 million people in the United States live with limb loss, and this number is expected to double by 2050. Scientists use the latest knowledge and technology to help these people by designing prostheses to retain the function and cosmetic appearance of a biological limb. Amputees commonly use myoelectric prostheses, which are controlled by the generated electromyographic impulse of muscles’ nerves to control the prosthetic.
Despite recent technological advances, control of myoelectric prostheses remains a
challenge. This challenge results in device rejection by the amputee and overuse injuries
of the intact limb. Learning to distinguish different muscle groups is a cumbersome
process hampering an easy adoption by the amputees. Therefore, the overall acceptance
of these devices is still low, leaving the amputees with an open problem to be addressed
by the scientific community.
We propose a novel vision-based design that uses an artificial neural network to help
amputees making an automated grasp. Building blocks of this design are: 1) an embedded
camera in the palm controlled by the amputee to take a snapshot of the object to grasp;
2) a trained convolutional neural network to identify the image of the object taken
by the camera and to find a suitable grasp type; 3) another differently trained convolutional
neural network based on finite element method to command and control a fine coordinated
movement of the prosthetic hand; and 4) a soft robotic prosthetic hand, controlled
by the second neural network to autonomously grasp the object.
This new intuitive technique is similar to how a human interacts with an object to
make a suitable grasp. People with a disability represent a significant part of our
society. We expect our results and outcomes to be of economic and medical benefit
to our community by providing a functional design and important knowledge for use
in commercialization of the future human prostheses. In the long run, we expect our
method to increase the quality of life for people with amputation by providing them
better ways of communicating their intentions and goals to their myoelectric prosthetic,
thereby reducing the support they need.

Peptides Therapeutics for Covid-19: Targeting the Protein-Protein Interactions of
Receptor Binding Domain and Angiotensin Converting Enzyme-2
The SARS-CoV-2 is a positive-sense single-stranded RNA (ssRNA) virus. This virus translates
four structural and many non-structural proteins. One of the most important structural
proteins is spike (S) protein which allows the virus to be attached into the host
surface by interacting with human angiotensin-converting enzyme-2 (hACE2) receptors
present in the upper and lower respiratory system. Recent studies show that the SARS-CoV-2
has 10-20 times greater affinity to the hACE2 receptors, resulting in greater transmissibility.
The S protein comprises of S1 and S2 domains. The S1 domain is responsible for binding to ACE2 receptors via its receptor-binding domain (RBD. The interaction between the receptor-binding domain (RBD) and the ACE2 receptor is the critical route of entry for the virus. Therefore, the S protein is a potential target for drug or vaccine development. Small molecules or peptides can be designed as therapeutics that will disrupt the interaction between the S protein and the ACE receptor; however, small molecules are not ideal for targeting the large protein-protein interactions (PPIs). Peptides, on the other hand, can disrupt the PPIs effectively as they possess larger surface compared to small molecules and thus specifically bind the interface binding region.
Our central hypothesis is that antiviral peptides which were known to inhibits SARS and other viruses can be repurposed and improved for effective covid treatment. Our group recently computationally screened antiviral peptides, that were known to work against SARS-CoV-1 and other viruses, targeting the receptor-binding domain (RBD). Based on Grace’s computational screening results during her First-Year Scholars program, some peptides were the most promising candidates which could potentially block the entry of SARS-CoV-2. During her sophomore scholar program, she will work on the following aims:
Aim 1: Based on the previous computational screening results, 5-6 peptides will be
synthesized using standard Fmoc-based synthesis protocols. The synthesized peptides
will be purified using RP-HPLC and characterized by mass spectrometry, and circular
dichroism (CD).
Aim 2: The inhibition efficiency of the best peptides against RBD will be performed by SARS-CoV-2 Spike-ACE2 Interaction Inhibitor Screening Assay Kit.
The expected outcome of this project to identify potent antiviral peptide and advance our knowledge of how these peptides can be further improved. The expected results will have a very positive impact on the public heath imposed by the Covid-19 pandemic.

Predatory Myxobacteria of the Longleaf Pine Ecosystem
Myxobacteria, a group of gram-negative rod-shaped predatory bacteria primarily found
in soil, kill and lyse their prey using antimicrobial compounds and lytic exoenzymes
and use the released nutrients to facilitate their growth. Myxobacteria are typically
found in soils with a neutral pH level. However, we have detected myxobacterial presence
in soil samples, with a pH range of 4.5-5.5, collected from the longleaf pine conservation
area in Paulding County by whole microbiome sequencing. The isolation of novel myxobacteria
is of great interest as they are a potential source of useful metabolites such as
antimicrobial compounds.
The goal of this project is to isolate wild myxobacteria from 48 soil samples collected
from the longleaf pine conservation area. The soil samples will be treated with antifungals
and placed on starvation media streaked with prey bacteria as bait in order to lure
myxobacteria from the soil. Isolated wild myxobacteria will be analyzed for their
predation capabilities against a range of clinically significant prey bacteria and
screened for the production of antimicrobial compounds.

Synthesis, Characterization, and Mass Spectrometry Studies on Scorpion Venom Peptides
to Develop Therapeutics Against SARS-CoV-2
The corona virus began a worldwide pandemic in the beginning of 2020, infecting over 605 million and killing over 6.48 million people worldwide as of August 27, 2022. Recently FDA authorized some vaccines for emergency use, however, the infection and death toll is rising each day, there is an urgent need for effective and selective antiviral drugs/peptides. Several small molecules have showed promising results for covid-19 treatment, however, very few studies have been performed for antiviral peptide therapeutics. Repurposing of drugs such as Remdesivir, Favipiravir and others exhibit some therapeutic efficacy against Covid-19. Therefore, development of new effective and specific antiviral agents and strategies are urgently needed to provide alternate therapeutic molecule to treat SARS-CoV-2. Antimicrobial peptides, isolated from living species, are potential broad-spectrum antiviral agents. Scorpion’s venom contains a mixture of peptides and proteins with varied bioactivities and receives a great attention due to their potential application in peptide drug design and development.
This novel RNA virus translates 29 proteins including 16 non-structural, 4 structural and 9 accessory factor proteins. Among all SARS-CoV-2 viral proteins, the main protease has important role for viral polyproteins maturation and replication. Drug repurposing provides a useful and effective solution for identifying potential therapeutics against SARS-CoV-2. The most successful 3CLpro inhibitor is lopinavir, a protease inhibitor used to treat HIV infections. This drug is also marketed as lopinavir-ritonavir as a boosted form. However, a clinical trial of lopinavir–ritonavir for adult patients with severe Covid-19 infection have not shown much promise. Despite some challenges, peptides have several advantages including high specificity and effectiveness, easy to synthesize, high potency, low toxicity, fewer side effects, and low accumulation in tissue. Our central hypothesis is that peptides which were known to inhibits protease of other viruses can be repurposed and improved for effective covid treatment.
During the sophomore Scholars program, Naom will conduct research with following specific
aims:
Aim 1: Based on the previous computational screening results, 5-6 peptides will be
synthesized using standard Fmoc-based synthesis protocols. The synthesized peptides
will be purified using RP-HPLC and characterized by mass spectrometry, and circular
dichroism (CD).
Aim 2: To assess the inhibition efficiency of the synthesized peptides, protease inhibitor
assay will be conducted.
The expected outcome of this project to identify potent antiviral peptide inhibitors
against 3CLpro and advance our knowledge of how these peptides can be further improved
for their efficiency through structural guided investigation. The expected results
will have a very positive impact on the public heath imposed by covid-19 pandemic.
In addition, our findings will help to address important strategies on designing peptide
therapeutics against the viral proteins.

Women Writers of Film & Television (WWFTV) Digital Humanities Project
Underway since Fall 2020, the WWFTV digital humanities project will culminate in a searchable digital archive to serve as inspiration for aspiring young women screenwriters and to provide industry professionals and screenwriting scholars easily accessible quantitative and qualitative scholarship on the works of women film and television writers. To date, there is no online resource dedicated to the study of women’s screenwriting contributions to U.S. and global film and television industries. As such, this project will serve as significant scholarship in film and television studies, offering a new framework through which to examine historical and contemporary screenwriting.
Students working on this project study current and pioneering women screenwriters and their most prominent works. Students research some of the top-ranked films and series in each decade and the genres where women have found the most success.
Students are searching online archives for interesting women writers whose work was
influential, well-received, or in some way intriguing in retrospect but, in many cases,
whose names are not commonplace to those who create, consume, or analyze film and
television. Student scholars are compiling genres or categories of films or television
shows that women often wrote for (e.g., soaps, afterschool specials, teen movies,
rom-coms, romance) and gathering information about the most compelling women from
each decade.
As we move into the next phase of the project, incorporating data into the website, students will draft new biographies, factcheck and rewrite existing biographies, update the database, and integrate fair use and public domain image links. Students working on the WWFTV project have obtained critical research and writing skills, as well as oral presentation skills as they share their research with their peers. Students have presented their research at the KSU Symposium of Student Scholars, the Southeastern Women Studies Association (SESWA) conference, NCUR, and the Posters at the Georgia State Capitol.
The WWFTV site is soft launching in September 2022 and hard launching in Summer 2023.
In the coming years, I will apply for external funding for WWFTV so I can continue
working with undergraduate researchers to build out the site. The ultimate goal is
to make the site comprehensive, including U.S. and global women screenwriters, which
will involve continual work to excavate data from the archives and update the site
as women screenwriters produce new works.

Exploring the Role of Individual Differences in False Confessions and Informant Behavior
In Cortney’s First-Year Scholars Program project, we conducted focus groups with students to explore students’ perceptions and experiences using the instant messaging app, GroupMe, in their college courses. Because Cortney is interested in topics in Psychology and Law, our plan is to involve her in a study investigating whether relationship status (friend versus stranger) impacts rates of false confessions and informant behavior. The data for this study are already collected. It was an experimental study that involved bringing two participants (either friends or strangers) into the lab and randomly assigning one participant to become our participant-confederate. Under the direction of researchers, participant-confederates cheated on test and later sent a plea to their innocent partner to take the blame for the cheating. Innocent participants were then falsely accused of cheating. Our primary dependent variables included false confessing (i.e., signing a statement indicating they cheated), engaging in informant behavior (i.e., stating they were an eyewitness to the participant-confederate’s offense, showing the text-message plea as proof of their innocence), and destroying evidence (e.g., erasing the text-message plea).
The plan is to have Cortney assist in identifying recent articles published to strengthen
the literature review, fill gaps in the coding of some data, and assist in analyzing
a portion of data from the study. As part of this study, participants completed individual
difference measures, including empathy, perspective taking, emotional intelligence,
and the Big Five trait measures (i.e., openness, consciousness, agreeableness, extraversion,
and narcissism). These data have yet to be analyzed.

Pathways to Purpose Among Marginalized Older Adults
This project aims to explore the pathways to developing and maintaining a sense of purpose among marginalized older adults. Previous research has primarily used quantitative, self-report measures to assess how older adults define and maintain a sense of purpose in life. Further, previous research has largely ignored how older adults who face challenges due to aspects of their identity may pursue and maintain a sense of purpose differently than those who are not marginalized. As such, our project seeks to fulfill these gaps through conducting one-on-one, semi-structured interviews with older adults who identify as marginalized. Twenty-two older adults will be interviewed and are currently in process of being conducted by the student. The semi-structured interview has been designed for this project and asks about older adults’ experiences with challenges that have acted as barriers for the development of their sense of purpose in life. The interview also asks about resources that have aided in the maintenance of purpose in life. Interviews are expected to be completed by the end of September, 2022. The next phase of the project will comprise of in-depth qualitative coding of the interviews. A grounded theory analysis will be performed. The student will first be trained in this qualitative method and will then conduct practice coding with a sample dataset. Coding of actual study interviews will then follow. Themes are expected to reveal the ways in which marginalized older adults have faced challenges that may act as barriers for the maintenance of their purpose and also what resources have helped them to develop a purpose. Findings are expected to be of practical relevance that may be used to develop interventions for older adults from marginalized communities.

Examining Factors and Interventions to Promote Personal Resources and Well-Being
This project explores how personal resources, which can be enhanced and promoted, are linked to individual's mental health, positive behaviors, and well-being (e.g., stress, work engagement, job boredom, positive affect) in different settings (i.e., work, school, healthcare, employment). One of the projects during participation in the FYS program consisted of implementing intervention programs related to personal resources and psychological well-being. This intervention is a brief program that aims to develop four malleable personal resources: self-efficacy, hope, optimism, and resilience. Promoting these personal resources enhances people’s ability to handle challenging situations, set and achieve goals, and engage in healthy behaviors. The program was implemented in a public organization in Puerto Rico. During Summer 2022, we started data analysis and writing of the manuscript. We expect to continue this work and submit the article for publication during Fall 2022. The student participating in the First-Year Scholars Program AY21-22 (Edwin Trejo Rivera) is collaborating on this project.
Currently, we are working on two projects to explore the interconnectedness of demands
and resources on stress, resilience, and work outcomes. The first project aims to
understand the precursors of work-related stress and well-being among nursing personnel.
As part of this project, we expect to identify the coping strategies used by nursing
personnel to deal with daily demands and the effect of job and personal resources
on their psychological health and performance. The second project aims to analyze
how the gender identity of women in managerial positions affects their psychosocial
well-being and their type of leadership. Specifically, in this project, we aim to
identify women's leadership style in managerial positions and further analyze how
the fit or misfit between the gender identity of women in managerial positions and
the stereotyped characteristic of the position affects psychosocial well-being. The
student will continue participating in these projects through the Sophomore Program
and actively participate in dissemination efforts (presentation and publications).

Detection of Trace Heavy Metals in Water: Development of Electrochemical Sensors
Modern industrial processes often result in release of heavy metal cations (such as
Ca, Cr, Hg, Cu, Pb etc.) in water bodies, causing adverse biological and ecological
consequences. Although, numerous techniques have been developed to detect heavy metals
in aqueous solutions, their early detection in trace concentration remains a challenge.
Electrochemistry based impedance sensors have gained considerable attraction due to

Novel Thermal Coating for High-Speed Airplane
In comparison to various other materials, carbon fiber, specifically carbon fiber
reinforced polymers (CFRP) remains pre-eminent amongst other materials for use on
aeronautical systems. Due to its high specific strength (strength-to-weight ratio),
CFRP has been able to carry heavy loads while maintaining a lightweight build. This
strength and weight efficiency has allowed for commercial airplanes such as the Airbus
A350 and the Boeing-787 Dreamliner to greatly outperform common aluminum frame airplanes.
Despite its extraordinary strength and light weight efficiency, when influenced by
heat resulting from air resistance, CFRP is known to undergo serious degradation that
would significantly decrease the effectiveness of the polymers. To prevent this degradation
and maintain the strength of the CFRP, thermal protective layers (TPLs) are designed
to shield the CFRP from heat exposure.
This research is focused on the examination of the effectiveness of TPLs, that are hybrid compositions of epoxy resins and buckypaper (carbon nanotubes) for 3K 2x2 twill carbon-fiber, through experimental methods. Experimental thermal analysis of the CFRP is performed at 225 °C for hot plate testing and 650 °C for heat gun testing. The results show that the addition of buckypaper in the thermal protective layer seemed to detect nearly 48°C less heat on average of the four measured intervals in hot plate tests. From heat gun tests, moreover, it was clearly seen that the carbon fiber TPL that contains the epoxy and buckypaper is dominant in terms of heat dispersion. The anisotropic thermal transport property of nanostructured carbon is expected to spread heat accumulated in hot spots efficiently, preventing the heat from being propagated into the CFRP body material. As the next step, we will use analytical method and FEA simulations to explain this heat dissipation phenomena.

Mechanisms of Trauma and Resilience: Extending Lessons Learned to Individuals with
Above ThresPTSD PTSD
Last year, KSU students and I examined the underlying mechanisms of resilience in the face of traumatic events by modeling the relationship between adverse events, anxiety, and post-traumatic growth while accounting for theoretical anxiety buffers that are predicted to moderate the detrimental effects of adverse events. Insights from this research not only informed broader literature and provide evidence for the theoretical framework of ABDT, but has laid the groundwork for research into interventions that target individuals’ natural resources and the cultural foundations that shape them. Students on this project presented at local and national conferences and have worked on products for publications. The current project will extend this work with a unique sample of individuals with above threshold PTSD. Data will be collected through Qualtrics for validation and normalized data modeling. Further, experimental designs will be employed to evaluate how mere thoughts of death can elicit similar (albeit far less in magnitude) responses to alleviate the anxiety associated with such adverse events.
Specifically, Quinn took on a special role last year by evaluating factors that he proposed should moderate the relationship between anxiety buffers proposed to reduce the psychological impact of a traumatic event on long term outcomes. Previous work supported Quinn’s idea to evaluate the stability of self esteem at the individual level and determine its role as a moderator in the broader model I had specified. His success has led our team to consider this a vital component to the validation study proposed for the coming year.

Still Racist, Sexist, Classist, and Ableist: Analysis of Children's Books
Children's books are an invaluable source of information and values. They reflect
the attitudes in our society about diversity, power relationships among different
groups of people, and various social identities (e.g., racial, ethnic, gender, economic
class, sexual orientation, and disability). The visual and verbal messages young children
absorb from books (and other media) heavily influence their ideas about themselves
and others. Depending on the quality of the book, they can reinforce (or undermine)
children's affirmative self-concept, teach accurate (or misleading) information about
people of various identities, and foster positive (or negative) attitudes about diversity.
Children's books teach children about who is important, who matters, who is even visible.
Therefore, carefully choosing and using quality children's books is an indispensable
educational and child-rearing task. It is important to offer young children a range
of books about people like them and their family's as well as about people who are
different from them and their family. All of the books should be accurate and appealing
to young children.
Fortunately, there are some good anti-bias children's books, which are available as
a result of the ongoing activism of many individuals and groups over many years. However,
while choices have improved over past decades, the lack of quality multicultural kids
books currently being published has frustrated many communities. The number of children
of color in the United States continues to rise, but the number of books published
by or about people of color stays the same or even decreases.
This research analyzes the recently published children's books and investigates if the books reproduce or challenge societal biases and prejudices on different groups of race, ethnicity, religion, gender, economic class, disability, and sexual orientation. The goal of the research is to report the current state of children's books regarding its role to teach children anti-bias understanding and, ultimately, to educate children better with anti-bias education.

Sustainable Building Materials of the Future: Architectural Forms and Structural Design
What will cities look like in 30 years from now? What is the future of building materials?
This research project seeks to bridge the gap between material science and construction,
looking at sustainable approaches in designing new buildings and infrastructures.
It can take decades for a breakthrough in engineering from a lab to a building site.
This research embraces the need for innovative architectural forms while building
upon structural design principles to create a new generation of smart materials.
Students working on this research project will investigate the use of sustainable
approaches in building materials of the future to (1) achieve more economical construction,
(2) improve sustainability and resilience, and (3) advance architectural forms and
forces.
The goal is to advance our fundamental understanding of cementitious materials and
their construction in an effort to marry architectural form and structural design.
The last hundred years in architecture and civil engineering have been widely dominated
by the use of concrete, which became the second most consumed commodity after water.
Although concrete and cementitious materials have a low embodied energy (of approximately
MJ90 MJ/kg), they are used in vast quantities. In 2019, cement production amounted
to approximately 3.2 billion tons, with production and usage accounting for almost
8-9% of total global anthropogenic greenhouse gas emissions.
This research aims to impact the embodied energy and the carbon emission associated
with new concrete constructions by possibly saving up to 30% in concrete volume compared
to an equivalent strength prismatic member. This research thus offers exciting opportunities
for engineers and architects to move towards a more sustainable construction industry.

Internships and the Job Market: How Remote Work Impacts College Student Careers
The National Association of Colleges and Employers defines an internship as "a form
of experiential learning that integrates knowledge and theory learned in the classroom
with practical application and skills development in a professional setting. . . .giv[ing]
students the opportunity to gain valuable applied experience and make connections
. . . giv[ing] employers the opportunity to guide and evaluate talent" ("Position
Statement" NACE). The American Association of Colleges and Universities and employers
universally recognize that internships are valuable, even essential, experiences for
college students with upwards of 96% of hiring managers opting to hire students with
one or more internships on their resumes over those who do not. Yet, we are living
in a changing world due to public health and economic concerns, especially during
the time of the COVID-19 pandemic, which has disrupted the global economy as well
as internships. This has also brought up forward concerns for college students and
employers about how to structure workspaces, who to recruit, and what jobs will exist
in the future. There is a need to not only understand the scope of the changes to
college internships in recent history as well as the landscape and opportunities for
the future.
Building on the research of Global Workplace Analytics, an organization that collects
data about telecommuting and remote work, this project will consider current data
that approximately 43% of the global workforce does a significant amount of work from
home as well as predictions that over 30% of the US workforce will continue working
offsite fulltime into the year 2021 . . . and into the future. This study seeks to
understand the changes in student internships, discern trends for the future, and
ascertain how to support students and employers engaged in remote internships. Through
an IRB-approved research protocol with surveys and student interviews the project
is guided by three key questions:
- What were the experiences and perceptions of KSU student interns during the COVID-19
pandemic, particularly those performing remote internships?
- What preparation and/or support would have strengthened their experiences, and how
can this be incorporated into student internship courses?
- What is the likelihood of more remote internships in the future?
The research gathered will be disseminated through a scholarly publication, including
a journal article and book proposal about college internship program design. The student
will learn how to develop survey instruments, conduct interviews, and analyze data.
The student will also become an expert on the tools and practices that will help students
thrive in remote work internships and jobs. The data is essential to help faculty
and administrators, as well as students and employers, understand how to modify internships
for the future. In short, if more employers will be hiring remote workers, students
need to be prepared to work from home, understand how to get those jobs, and know
how to succeed outside of traditional office spaces. In addition, more information
is needed about best practices for remote internships and the future of the college
internships.

Women Genre Writers in Film and Television
In this project, students will research women’s work in writing for film and television. Students will research some of the top-ranked films (and series) in each decade and the genres where women have found the most success. Students working on this project will be searching for interesting women writers whose work was influential, well-received, or in some way intriguing in retrospect, but whose names are not commonplace to those who create, consume, or analyze film and television.
Student scholars will compile genres or categories of films or television shows that
women often wrote for (e.g., soaps, afterschool specials, teen movies,coms-coms, romance)
and gather information about the most compelling women from each decade.
This is an excellent opportunity for students with an interest in film and television, screenwriting, or women’s representation in media to explore online archives and obtain critical research skills. Students should be comfortable working independently and under faculty supervision and should be willing and eager to conduct most research on their own.
*Here are some interesting statistics about women’s work writing for film and television in the past few years:
- 2018: women accounted for 16% of all writers working on the 250 top-grossing films.
- 2019: women accounted for 19% of all writers working on the 250 top-grossing films.
- 2017-2018: women accounted for 25% of all writers working on broadcast network programs
- 2018-2019: women accounted for 35% of all writers working on broadcast network programs

Perceptions of COVID 19 among Religious Leaders: Implication for Health Messaging
in Faith Communities
The purpose of this study is to examine perceptions of COVID-19 among faith leaders,
specifically:
- What is the prevalence of religious interpretations of COVID-19 (the illness as a
result of sinful behavior, as a sign of the coming end of times/day of judgement,
the illness as a test from God, karma, etc.)?
- Where do faith leaders turn to for information about COVID-19?
- What protective health behaviors are faith leaders engaging in to avoid contracting
COVID-19 and what is their perceived risk of contracting the disease given their community
role?
- How do faith leaders translate their own beliefs and external messaging into communications
for their communities? To what extent do they view health communication as a responsibility
within their position?
This study will use anonymous surveys to examine perceptions of COVID-19 and health
behaviors related to COVID-19 among faith leaders from various faith backgrounds.
The second phase of the study will utilize virtual focus groups to discuss in depth
how health policy and religious policies, as well as theological interpretations of
illness and suffering intersect to impact how faith leaders communicate information
regarding COVID-19 to the religious communities they lead. This mixed method approach
seeks to gain descriptive evidence of the prevalence of religious and spiritual interpretations
of the disease, as well as understand how these interpretations shape faith leaders'
messaging, particularly health information and meaning attributions shared with their
communities. This study will use a multi-modal, mixed methods approach. Initial descriptive
research to measure perceptions of COVID-19, health protective behaviors used by faith
leaders, and how they communicate with their communities during social distancing
will be collected through an anonymous internet-based survey. This survey will be
distributed directly to faith leaders via email and through religious community hierarchy
(for example, a District Superintendent may be requested to share the survey link
with their pastors, or an imam may be asked to share the survey with other imams).
Additionally, participation will be solicited via Social Media, specifically Facebook
by posting on the Investigators page, and sharing on pages dedicated to religious
communities.
The second phase of the study will involve conducting 4 different focus groups with
6-8 participants through Zoom. These focus groups will last approximately 40 minutes
and allow for in-depth discussion of:
- How religious perspectives, public health policy, and other factors influence how
faith leaders view Covid-19 and interpret the suffering caused by this illness
- How these interpretations translate into public communication with faith followers

Self-Driving Cars are Coming but You Still Need Driver-Training Programs
Summary: Self-driving cars are already on the road. However, they are not perfect.
Human drivers are still responsible for monitoring the driving status of the vehicle
and step in when it is necessary. Therefore, experts point the importance of research
on effective monitoring of the driving status by human drivers and smooth transfer
of control from a vehicle to the driver. In this driving-simulator project, we will
examine how human drivers behave when self-driving cars are malfunctioning. Specifically,
we will identify (1) the signs of malfunctioning/incapability of the self-driving
cars that are frequently missed by human drivers and (2) undesirable responses that
human drivers make when they attempt to regain control of the vehicle. Finally, we
will (3) generate a list of recommendations for a driver-training program that improves
the monitoring/handling ability of drivers.
Developing a driver-training program for safer use of motor vehicles has evident importance
considering the noticeably high fatality on the road: for example, an average of 101
people was killed in motor vehicle crashes per day in 2018. Motor vehicle fatality
is also the leading cause of accident death among adolescents. This research project
was developed to reduce fatality on the road in the era of self-driving cars.
A self-driving car is a vehicle that can sense its environment and perform the dynamic
driving task with little or no human input. As an example of the self-driving technology,
a driverless-taxi service has been commercialized in the Phoenix metropolitan area
since December 2018. As expected, the technology has been developed with a promise
of offering safer and convenient travel. However, such promises have been betrayed
by fatal crashes and unexpected handover of vehicle control from the car to the human
driver especially when the driving conditions are difficult to handle.
In the field of aviation, although the autopilot technology has been developed decades
ago, human pilots are still required to monitor the status of the airplane and step
in when it is necessary. Similarly, human drivers of self-driving cars are expected
to recognize the signs of malfunctioning/incapability of the car and skillfully step
in when it is necessary. However, there is not enough research for improving such
abilities of human drivers.
In this project, we will examine how human drivers behave when self-driving cars are
malfunctioning using driving simulators with a steering wheel and brake/accelerator
pedals. The simulators will present various scenarios of malfunctioning/incapability
of the self-driving technology on computer screens where each scenario includes unique
signs of the malfunctioning. Participant drivers will be asked to monitor the driving
status of the car and step in when they believe it is necessary.
We will identify:
1) the frequently missed signs of malfunctioning/incapability of self-driving cars
and 2) desirable/undesirable reaction patterns of human drivers when they unexpectedly
step in and control the vehicle.
Finally, we will 3) generate a list of recommendations for developing a driver-training
program that improves the drivers ability to recognize critical signs of incapability
of self-driving cars and how to react in such scenarios.

Joking, Juries, and Jurisprudence: Informal Communication in a Formal Workplace Setting
This project explores the use of humor to cope with workplace stress, particularly
the legal profession. For the purpose of this project, the legal profession has been
narrowed to the courtroom. Furthermore, we are interested in how judges, court reporters,
and attorneys communicate to cope. The courtroom is a tense workplace. Humor has long
been studied as a coping mechanism in a variety of demanding and emotionally draining
work scenarios. The litigation field (courtroom law) has a high burnout rate. This
project would frame an argument that informal communication and humor serve as survival
skills to persevere in a challenging profession.

Health Disparities: The Impact of Race, Class, Gender, and Sexuality on Health Outcomes
Our main goal is to live a long and healthy life. Unfortunately, being sick is a part
of life. Whether it is a sudden acute injury or a long drawn out chronic condition
or a serious life limiting disease, we will all experience the consequences of illness
in some capacity. While illnesses can be reduced to their biological causes and clinical
treatments, there is much more to being sick. Social factors, including race, ethnicity,
socioeconomic status, gender, sexuality, and even issues like age, religion, and geography,
also play an important role in promoting health and preventing disease. Moreover,
social determinates of health, or conditions in the environments in which people are
born, live, learn, work, play, worship, and age, significantly affect a wide range
of health, functioning, and quality-of-life outcomes and risks.
My research projects are very multidisciplinary, combining aspects of biology, psychology,
sociology, public health, nursing, statistics, human services, education, business,
etc. These projects aim to shape how people think about and eliminate health disparities
through investigating how social, economic, environmental, cultural and lifestyle
factors contribute to differences in morbidity and mortality within certain populations
and communities. I currently have three large-scale National Institutes of Health
(NIH) funded projects specifically looking at the intersections of race, class, gender
and sexuality on chronic conditions utilizing both qualitative and quantitative research
methods. Additionally, I investigate how social issues related to systemic racism,
poverty, sexism, and homophobia contribute to lack of appropriate healthcare access.
I work with both patients and healthcare providers to identify and combat barriers
to care for many underserved populations. My research projects also include research
questions related to ethical decision-making, cultural competency, health literacy,
and behavior change. Because you cannot separate mental and physical health, my projects
focus on both as well as the influence of physical health on mental health and versaversa.
Given the current opioid crisis, I also try to integrate the impact of substance use
disorders on many health outcomes, which is even further compounded by issues of race,
class, gender, and sexuality. Since KSU is located at the crossroads of urban and
rural living, I also stress how geography contributes to people's experiences with
health and illness.
In addition to collecting both qualitive and quantitative data to better understand
health disparities, I am also interested in actually developing and implementing new
programs and approaches to promote health, prevent disease, and ensure health equity.
This includes self-management interventions, educational programs, and policy improvements.
Instead of being restricted to a traditional laboratory, the world is my lab. My research
collects data from real people in the real world, allows us to pivot our research
questions depending on the findings, and supports interventions and programs that
will benefit people right now, contributing to a healthier world.

Messages Gone Viral: How Infographics About COVID-19 Spread on Social Media
Have you ever wondered why people share some visuals about COVID-19 online and not
others? What makes a good message about COVID-19 to share on social media? Come and
work with Dr. Doan to find out! You'll learn about what visual design principles encourage
people to engage with health information online by gathering a collection of charts,
graphs, and infographics from social media sites like Facebook, Twitter, and Instagram.
You'll use nVivo, a software available through the university, to collect and tag
these images. Next, you'll learn to sort these social media posts to understand what
types of written messages (encouraging behavior like mask wearing, sharing statistics,
etc.), visual design tools (like color, contrast, typography), and types of posts
(an infographic, a chart, etc.) are engaged with most online. After we make our research
categories into a formal codebook, you'll learn how to conduct inter-rater reliability,
a way of testing our codebook with outside users to make sure that it makes sense
outside of the original coding. Then, we'll write about, and hopefully publish, our
results to help designers, public health officials, and people who run social media
campaigns use our work to design more engaging posts about how to help people understand
and stop the spread of COVID-19.

On-board Wave Energy Harvesting for Sustainable Boats and Ships
Ocean wave is an abundant source of clean energy which offers great advantages over other renewables, such as its availability during both day and night times and much higher energy density compared to wind and solar. Currently, there are no viable or commercial technology available to harvest wave energy by individual boats and ships. In the United States only, there are more than 87,000 commercial fishing vessels and more than 100,000 recreational fishing boats. The world fishing fleet exceeds four million vessels, most of which are gasoline powered and release tons of polluting, toxic and greenhouse gases into the environment. In this project, we propose a novel hybrid wave energy conversion (HWEC) device that can be easily integrated and retrofitted into a boat or a ship to harvest renewable energy from the ocean waves and produce on-board electric power. This technology will reduce the dependence on gasoline – thus reducing the polluting and greenhouse gas emissions and mitigate the global warming effects.
The aim of this project is to design and fabricate a prototype of the proposed magneto-piezoelectric hybrid wave energy conversion device by applying electrical engineering and energy conversion principles resulting in a low-cost, modular HWEC device that can be easily retrofitted inside a fishing vessel or any other types of boats or ships – mounted underneath the decks, onto the floors or virtually anywhere on the vessel to produce clean electrical energy. The technology is scalable and could be easily adapted to next generation of all-electric commercial vessels, as well as navy ships. The first-year research scholar will gain valuable knowledge on renewable energy harvesting techniques from ocean waves, receive hands-on training and develop important and useful engineering research skills through this project.

Minimizing Power Losses in Solar Photovoltaic Systems
Solar Photovoltaic (PV) systems generate electric power by converting sun light into
electric power. Due to its cleanness and sustainability, there has been growing interest
in building solar PV projects over the world replacing traditional fossil fuels-based
power plants. One of the problems facing solar PV projects is their lower efficiency.
A major factor limiting their efficiency is partial shading which occurs when part
of a solar system is shaded by a tree, cloud..etc. This project is to reduce the power
losses experienced by solar PV systems when they are partially shaded. The project
uses a novel algorithm that optimizes power extraction during partial shading.

STEM Mentor-Protege Program with Marietta Schools Using the Texas Instrument TI-RSLK
as a Tool
With existing relationships with Marietta Schools and the Development assistance from
Texas Instruments TI, this effort will use the Texas Instrument Robotic System Learning
Kit (TI-RSLK), to foster and further develop the pathways for a STEM Mentor-Protege
Program between the Electrical & Computer Engineering Department Students & Faculty,
and the Marietta Schools' Teachers and Middle/High School students (especially Females
& Minority students), to create and nurture a sustainable STEM-Pipeline. This can
then be further developed to also provide a foundation for possible responses to RFPs
from Agencies such as the National Science Foundation NSF, in the foreseeable future.
In the broader sense, this Research effort will lay the foundation for a Sustainable Mentor-Protégé, STEM-Student-Pipeline (especially for Females and Minority students). Students working on this project would be exposed to both the foundations and deeper understanding of how electronic system design works. They will also be involved in the processes of affordable Design, Build & Test activities.
The TI-RSLK will allow students working on this project to learn about Robotic Systems
and the Engineering Applications associated with them. Texas Instruments will supply
the Project with several TI-RSLK Robots for Hands-On activities throughout the effort.
At the end of each Program period, students would have demonstrated the value of the
following: Mentoring relationships and the role that gender plays in STEM mentoring,
particularly cross-gender mentoring relationships and whether they encourage positive
socialization to the field in the same manner as same-gender mentoring relationships.
- Mentoring relationships and the role that gender plays in STEM mentoring, particularly
cross-gender mentoring relationships and whether they encourage positive socialization
to the field in the same manner as same-gender mentoring relationships
- The role of gender in different types of mentoring models and in the terms of mentoring
relationships (i.e., formal or informal). For instance, studies could examine whether
males and females in STEM fields receive the same benefits through formal and informal
e-mentoring programs or whether mentoring relationships that utilize the citizen model
facilitate the retention of females within STEM disciplines
- The elements of successful mentoring relationships formed by females in STEM disciplines

Mechanical Responses of Lipid Vesicles Under Different Hydraulic Environment
Mammalian cells are protected by a plasm membrane made of lipid bilayers. This membrane is highly deformable under various mechanical conditions, creating different morphologies for cells. My prior studies have shown that the responses of cells are highly sensitive to extracellular hydraulic pressure, which is particularly prominent when cells reside in confined spaces. Although cells are living systems that respond actively to environments, they as enclosed vesicles respond passively to physical conditions in the first place. Differentiating the passive and active responses will help us better understand how cells adapt to environments and carrier out functions. It is challenging to differentiate the two types of responses in living cells; however, using liposomes will enable us to focus the study on the passive responses.
In this interdisciplinary study, we will use both mathematical and experimental models
to study the responses of passive liposomes. In particular, we will construct liposomes
and observe their morphologies and motility under various hydraulic environments.
The mathematical models will be developed on continuum mechanics and will be programed
in MATLAB. The prediction from mathematical models will serve as guides to further
design meaningful experiments.

Exploring the Effects of Spaceflight Microgravity on Blood Flow and Cardiovascular
Disease
Long-duration spaceflight poses multiple hazards to human health, including physiological
changes associated with microgravity. A recent study reported the existence of blood
flow abnormalities in the jugular veins of six astronauts participating in long-duration
spaceflight missions aboard the International Space Station, and an occlusion in the
vein of one more. Although the cause-and-effect relationships between microgravity,
blood flow alterations and cardiovascular disease have not yet been elucidated, it
is well known that the vasculature is sensitive to its surrounding mechanical environment.
Abnormalities in the fluid stresses imposed by blood flow on the surface of blood
vessels for example are known to trigger inflammatory responses that may lead to cardiovascular
disease. In this context, the hemodynamic alterations resulting from spaceflight microgravity
may trigger a biological response leading to disease. Testing this hypothesis requires
the characterization of the stress environment experienced by the vasculature under
microgravity. To address this research need, we propose to develop computational fluid
dynamics models of the human carotid bifurcation under unit gravity and modeled microgravity
conditions, and to quantify their fluid stress characteristics on the arterial wall.
This work will enable future investigations of the risk posed by spaceflight microgravity
on cardiovascular disease.

Development of Wire Actuated Monolithic Soft Gripper Positioned by Robot Manipulator
Robotic grippers integrated with end effectors have been widely used to pick and place
targeted objects or assemble parts in the automation industry. Grippers are commonly
attached as an end effector to the multi-link robots to change its orientation, and
the performance of the gripping motion highly depends on the design of the gripper
itself. Rigid mechanisms designed by traditional links and joints exhibit low performance
compared to compliant mechanisms due to the friction, clearance, and backlash. A mechanism
is said to be underactuated if the number of actuators is less than the degrees of
freedom of the system and adaptive if the mechanism response adopts to the new environment.
This project aims to design and develop an adaptive wire actuated compliant gripper mimicking human hand. The compliant gripper will be oriented through a 2D link robot. The configuration of the robot will be actuated by servo motors. The robot and the gripper will be 3D printed using polylactic acid (PLA) and thermoplastic polyurethane (TPU).

Development of Soft Fluidic Sensor for Body Motion Sensing
Stroke rehabilitation is very important for recovery after stroke. The patients need to exercise regularly and their progress should be monitored. Thus, development of body motion sensors which can detect the motion and performance of patients would be very important. The sensor data can be sent to medical centers to monitor the progress of the patients. This project aims to develop soft motion sensors which can safely interface with human body to measure large motions/deformations.
The proposed soft sensors generally consist of a patterned balloon and a fluidic pressure
sensor. As the balloon being stretched and deformed the internal pressure of the balloon
will change. Consequently, the pressure reading can be correlated to deformation of
balloon to create a motion sensor. The balloons can be fabricated from thermoplastic
materials or silicons by means of molding, and thermoforming.

Biology to Biotechnology - Mimicking BATS sensing behaviors on Mobile Robots
In mobile robot research, the robot needs to answer three main questions in order
to make it navigate.
- Where am I?
- Where am I going?
- How do I get here?
In order to address these questions on the Robotic Platform, we follow guidelines
for the environmental model, for the interpretation and examination of the environment,
for the location and condition of the system and for the planning of the movement.
As we see, BATs navigation in the forest will resolve all the above questions by merely
transmitting a sound wave and having to know the environment by hearing the echo.
In the first part of the project, we will concentrate on creating a simulation environment like a forest and making our robot maneuver through acoustic laws.
The second step is to verify this strategy with a real robot and how fast the sensor
is responding. But, on a larger scale, we can solve a lot of payload problems on robots and only
set up a simple acoustic sensor to get to know the whole area.

Building a Digital Database to Document Photography and Carved Ivories
Establishing an organized database is foundational to documenting, preserving, presenting
and interpreting historical materials. For this project, the student will collaborate
with the faculty member in the ongoing development and analysis of a digital database
to record photographs and carved ivory sculptures produced during the late 19th century
in the Congo, Central Africa. These materials are housed in archives and museum collections
throughout the United States, United Kingdom and Europe. While a single or digital
images may capture an archived photograph, each carved ivory sculpture is documented
through hundreds of digital records that collectively capture the details of each.
With thousands of carved ivories housed in museum collections, the digital database
continues to grow. While travel restrictions due to Covid-19 has put a temporary halt
on onsite production of digital records by the faculty member, the organization, refinement,
cataloging and analysis of already collected records continues.
Over the course of the year the student will contribute to the development of this
database by editing, organizing and cataloging digital records and analyzing archival
content to develop thematic clusters for conference presentation and potential publication.
By conducting this work the student will contribute to the first-ever visual database
on early colonial-era photographs and carved ivories from the Congo. This database
serves as the primary source for the writing of a postcolonial African Congo history
in counterpoint to established colonial narratives. The database will be utilized
by source archives, museums and scholars in the field and serves as reference material
for historical research and future publication. This is an opportunity for a student
to gain experience in developing primary research skills relevant to archives, art
history, history, anthropology, and museum collections management and to hone technical
skills in image editing.
Students interested in this project should be comfortable working with MAC computers
and have a firm working knowledge of programs such as Excel, Photoshop, and Illustrator.
Students in African and African Diaspora Studies, French, History, Anthropology, Art,
Art History and Education are particularly welcome. Students should be able to work
independently and under supervision through virtual meetings. An ability to read French

Broadening the Western Music Theory Canon
Working with faculty, students will help survey a variety of print music sources of
underrepresented composers and music genres in the Western Music Theory canon. Project
will evaluate, identify, and classify musical examples and excerpts to augment existing
introductory undergraduate music theory and aural skills course materials. In addition
to assembling materials to augment existing KSU curriculum, materials will be shared
through a wider academic and educational readership, as possible.

Building Modern Services with Security Assurance in the Edge Infrastructure
This project aims to address these critical security issues by using adaptively data-driven
execution model in the cloud-edge systems, including various IoT devices, and revisiting
how they affect resource management and energy consumption. It also helps in learning
and usage of resource control as the IoT devices should be capable of running two
or different applications on the same time. The goal of this project is to explore
the possible solutions to improve the security of the modern edge services and propose
solutions to advance the reliability of the edge infrastructures.
Specifically, this project will help you achieve the following outcomes:
1) Understanding the techniques and concepts of using these IoT devices for better
implementation; 2) Analyzing the semantic gaps in the cloud and the edge, and design augmented abstractions
to bridge the gaps; 3) Using the data-driven execution model to provide effective, efficient, and secure
components; 4) Increasing the fundamental understanding of cloud-edge systems in resource management
and energy control.

Molecular Cargo Delivery into Bacteria; Delivering the Goods
Common bacteria are very easy to grow and study in a research lab. They are interesting because many have useful abilities such being able to degrade toxic waste products, producing antibiotics or for food production, such as yogurts and cheese. It is also relatively easy to manipulate bacteria to do even more useful things we want them to through genetic engineering. Of course, there are also some bacteria that are harmful to humans. Our lab is investigating a molecular approach that may allow us to modify good bacteria or selectively target harmful ones for destruction.
The Griffin lab has recently demonstrated that a cell-penetrating molecule called TAT-CaM, developed in the lab of Dr. Jonathan McMurray at KSU for mammalian cells, can be used to deliver cargo proteins into eukaryotic fungal cells. We want to now determine if this molecule can also be used in bacterial cells. We seek to determine the diversity of the cargoes accepted for delivery and the limitations of what can be moved that are both beneficial and toxic. This is of particular importance if this system is to be used for industrial and biotechnology processes as well as for the potential therapies against medically-relevant bacteria.

How to Make a Brain in Three Easy Steps
The Hudson lab at Kennesaw State University is broadly interested in: (1) understanding
how cells in the body become neurons; and (2) how neurons connect to one another to
make neural circuits and how those circuits control an animal's behavior. To do this,
we primarily use the nematode Caenorhabditis elegans as a model for these studies.
Nematode worms have many advantages for studying the nervous system. First, they have
an invariant cell lineage, which means that whenever a cell divides, we know exactly
what its daughter cells are going to be. Second, they're see-through, which means
that we can actually see neuronal cell bodies and axon bundles without having to dissect
the animals. Third, we can use fluorescent reporter genes to label individual cells
in the worm's brain. Finally, we can use genetics to change the underlying genes required
for nervous system development and function. By creating mutations that change the
fate of a neuron or the shape of an axon, we can figure out which genes are required
for making the nervous system and how that affects behavior. Is this relevant to humans
and human neurological disorders? Oh yes! The genes required for shaping the worm's
nervous system are the same genes required to shape the human nervous system. As such,
we can look at the worm version of human disease genes and understand what the consequences
are for mutating that particular gene and how it affects nervous system development
and function. We have two main projects on-going in the lab. The first one is to examine
a class of proteins called transcription factors to figure out how they affect whether
a cell becomes a neuron or something else. Second, we are examining how sensory neural
circuits connect together, and whether defects in nervous system connectivity lead
to behavioral defects.

Environmental Impact on Decision Making in Ecological Communities
Evolutionary game theory (EGT) is a mathematical framework through which we can study
decision making in ecological communities. As the name suggests, EGT borrows ideas
at the heart of game theory, which can be very generally defined as the study of decision
making in competitive situations. By considering interactions between individuals
occupying the same ecological niche as games, we can utilize the extensive toolset
offered by classical game theory to understand when these individuals should cooperate
or when they should "defect" as the terminology goes. Researchers have made great
strides over the past 50 years both expanding the mathematical understanding of EGT,
and applying it to study a wide range of biological systems, from bacterial communities
to social vertebrates to cancer cells.
This project will focus on a recent branch of EGT that couples game theoretic decision
making with a simple model of the surrounding environment. These so-called "ecol-evolutionary"
models allow us to study environmental impact on ecological interactions, and helps
address important questions related to environmental uncertainty due to climate change,
over-harvesting or overgrazing, or simply environmental effects of the seasons. Students
will help develop mathematical models, study systems of differential equations both
analytically and using computer software (MATLAB), and possibly study simple stochastic
systems (if interested!).
