Student Research Poster Presentations 2026

Microplastics Effect on Gut Microbiota 

PELLEW, V, Misericordia University, 301 Lake Street, Dallas, PA, United States, 18612

Microplastics (MPs) are small plastic particles less than 5mm in size that are present throughout the environment and are commonly found in both food and water, making human exposure unavoidable. Ingestion occurs through consuming contaminated food, inhalation by breathing airborne particles, and dermal contact via phone cases or skin care products. Once absorbed into the body, MPs may influence human health by altering the gut microbiome.

Results from human fecal studies and in vitro models have shown that MPs can alter pathways associated …

Pressure Field Estimation From 2d-Piv Measurements: A Case Study Of Fish Suction-Feeding, Jensine C. Coggin, Duvall Dickerson-Evans, Erin E. Hackett, Roi Gurka

Marine Science

Particle image velocimetry (PIV) flow measurements are common practice in laboratory settings in a wide variety of fields involving fluid dynamics, including biology, physics, engineering, and medicine. Dynamic fluid pressure is a notoriously difficult property to measure non-intrusively, yet its variation is a driving flow force and critical to model correctly. Techniques have been developed to estimate the pressure from velocity and velocity gradient measurements. Here, we highlight a novel application of boundary conditions when applying such pressure estimation techniques based on two-dimensional PIV data; the novel method is especially relevant to problems with complex boundary conditions. As such, it …

Generalized linear models were used to assess the relationships between out-of-system movements and biological and environmental variables. Results Most Common Snook departures took …

Overbreadth In Medical Practice Acts: A Threat To Preventive Speech, Barbara Zabawa

Faculty Works

Many Americans consult unlicensed wellness coaches for scientifically-valid advice on diet, exercise, and lifestyle interventions. Yet state medical practice acts and ambiguous government line drawing between wellness and medical care chill the speech of these coaches as it relates to disease prevention, even though conventional medicine systematically fails to deliver the speech-heavy preventive care consumers need and want. This Article argues that medical practice acts, particularly the sixteen state statutes that include "prevention" in their definition of medical practice, are constitutionally overbroad restrictions on protected speech. Despite judicial and scholarly assumptions to the contrary, not all those working in wellness …

In Vivo Telemetry To Record Long-Term Cardiovascular Parameters, Temperature, And Activity In Spinal Cord Injury Rat Models, Sajeev Kaur, Anna M. Baur, Jillian A. Condrey, Dorottya P. Gal, Samir P. Patel, John C. Gensel

Spinal Cord and Brain Injury Research Center Faculty Publications

Higher-level spinal cord injury (SCI) above thoracic level 6 (T6) disrupts autonomic function and contributes to secondary complications, including fluctuations in blood pressure, heart rate, and temperature. In rats, the placement of telemetric implants in the descending aorta offers a robust methodology for assessing various cardiovascular parameters, such as systolic and diastolic pressure, mean arterial pressure, and heart rate. Core body temperature and animal activity can also be recorded following telemetric implant placement. A rat with a telemetric implant is kept on the receiver plate connected to a computer system for recording various parameters. Continuous long-term recordings at defined time …

Missionaries And Magic: Freed People, Conjure And Reformation During Southern Reconstruction, Sanaa Belton

Undergraduate Research Awards

I argue in the pages to follow that during the Reconstruction period, reformation efforts by white northern activists attempted to shift the perception of Conjure from a dangerous yet useful spiritual tradition that served both the enslaved and their enslavers, to a spiritual tradition representative of a savage and backwards African people. Mainstream religious movements of the 1800s, the same movements that contributed to the prohibition of alcohol in the 1920s and early 1930s, were centered on the moral reformation of the United States. Missionary societies that branched off from these larger religious movements sent workers into southern states to …

The Legal Philosophy Behind Zoos Confinement Of Animals, Jamie Lynn Tucker Crockett

Undergraduate Theses, Professional Papers, and Capstone Artifacts

In my essay, I will be diving into the controversial issue of Animal containment, focusing on zoos in the United States. I will be taking this opportunity to establish a new way of thinking about the argument which states the pros of zoos outweigh the negative effects they have on the animals who live there. Neither side of the argument has a malicious intention towards harming animals. Instead, each side shows a different approach of what it is to properly care, and respect for animal rights. Those arguing in support of zoos commonly reference arguments dating back to Aristotle. However, …

Increasing Temperatures And Heatwave Durations Negatively Affect The Performance Of A Dietary Generalist, Kailey G. Hicks, Claire Guzinski, Mariana Abarca, Mayra C. Vidal, Audrey M. Mitchell, Dhaval K. Vyas, Shannon M. Murphy

Biological Sciences: Faculty Publications

Climate variability has increased in recent decades, and this trend is predicted to continue. Globally, there is a rise in extreme temperatures, such as heatwaves, which are strengthening in both intensity and frequency. As ectotherms, insects are especially affected by temperature variation. Insects are the most speciose group of animals and important members of most terrestrial ecosystems, providing critical ecosystem services. Most studies of global change have investigated only a single stressor, yet insects rarely experience one stressor at a time. Two stressors that co-occur are heatwaves and warming temperature regimes; thus, is it important that we study their interaction …

The Use Of Virtual Reality In Ptsd Research And Practice, Kenneth B. Abrams, Lindsay Okindo, Marta E. Bacon, Yiking Skylar Yu, Sofia Santamaria Germani, Malvika Malhotra, Nancy A. Cullen

Psychology Faculty Work

In the aftermath of traumatic events such as combat, sexual violence, or a natural disaster, individuals may develop posttraumatic stress disorder (PTSD). Technological advancements in virtual reality (VR) over the past few decades have opened new avenues for improving the assessment, treatment, and understanding of PTSD. VR allows users to be immersed in interactive, computer-generated environments that simulate real-world scenarios, such as a warzone or assault location, that would be difficult or unsafe to reproduce using traditional methods. The present paper offers an overview of how VR technology has been employed in both clinical and research settings related to PTSD. …

To address these needs, five classroom sensory kits were developed and distributed to one preschool …

Decomposing Shadow Prices Under Climate-Driven Growth Scenarios: Insights From An Elk Herd Case Study, Ranjit Bawa, Drew Bennett, Wai Yan Siu, Bailey Kirkland, David Finnoff, Jacob Hochard

ODU Articles

Natural capital accounting provides a framework for integrating ecological processes with economic valuation, but the mechanics of shadow price formation often remain opaque to resource managers and policymakers. Using the Clarks Fork elk herd in northwestern Wyoming as a case study, we decompose the shadow price of natural capital into its ecological, economic, and institutional components. Population dynamics are estimated using a linearized Ricker model and projected forward using a logistic projection, incorporating climate-driven reductions in intrinsic growth rates. These ecological scenarios are linked to a shadow pricing formulation that explicitly accounts for marginal benefits, harvest policy responses, discounting, and …

Cover Crop Effects On Soil Porewater Nutrients And Hydrothermal Properties, Md Mahadi Hasan

Theses and Dissertations

Adoption of winter cover crops in the U.S. Midwest may reduce nitrogen (N) and phosphorus (P) leaching from soils, potentially shrinking the hypoxic zone by limiting nutrient runoff into the Gulf of Mexico. To evaluate the impact of selected winter cover crops on soil porewater N and P concentration, a field study was conducted at the Illinois State University Research Farm (ISURF) and the Western Illinois University Research Farm (WIURF). The experimental design was a block experiment with four replications.  Cover crop treatments included a winter fallow, wild pennycress (WPC), golden pennycress (GPC), cereal rye (CR), annual ryegrass (AR), and …

Secret-Keeping Experiences Of Young Adults, Jace C. Griffith

Theses and Dissertations

In 2020, researchers Frijns et al. called for a new wave of secret-keeping research which prioritized the person-centric experience of youth keeping secrets. This study added to that collection by comparing two kinds of secret-keeping which are not compared in existing research: secrets which are related to abuse, and secrets which are not. Researchers in the field of child welfare study only abuse-related secret-keeping, almost always qualitatively. Alternatively, researchers of non-abuse secret-keeping or general secret-keeping collect almost entirely quantitative data, absent of the personal experience of secret-keeping.

Through an online survey, 205 undergraduate students were asked to reflect on an …

Effects Of Compost Incorporated Versus Surface Applied On Soybean Yield And Soil Health, Maheshwari Kuchanapally

Theses and Dissertations

Compost application is increasingly recognized as a sustainable soil management practice that enhances soil health and crop production. However, the method of application, incorporated versus surface applied, may influence its effectiveness in improving soil properties and crop productivity. This study evaluated the effects of compost application method on soybean (Glycine max L. Merr.) yield and soil health at Illinois State University Research Farm in Lexington, Illinois, across two growing seasons, 2024 and 2025.

Creating "An Exemplar Of A Better World": A Dialogic Analysis Of Academic Freedom Surrounding Columbia University Activism From 2023-2025, Ellanore Foltz

Theses and Dissertations

From October of 2023 to August 2025, the community at Columbia University engaged in a series of debates regarding the meaning of academic freedom. Academic freedom, first institutionalized in the United States during the first world war, has shifted over the decades as the purpose of higher education and the threats to higher education changed. In recent years, campus protests regarding Israel and Palestine have sparked new debates about academic freedom that reflect ongoing and sometimes fundamental disagreements about higher education. This study utilizes Relational Dialectics Theory (RDT; Baxter, 2011) to explore the interplay between different discourses of academic freedom …

Reawakening Waⁿdat: Community Research & Reclamation, Darcy Allred

Theses and Dissertations

The Wyandot(te) have undergone language dormancy due to settler colonial impacts of warfare, refugee relocation, forced removals, and U.S. assimilation projects. One of the most pressing priorities among our people today is reawakening our ancestral language, Waⁿdat. The common follow-up question is: how? Through the conduit of Waⁿdat language reclamation, this project grapples with the above question in collaboration with the Wyandot(te) community, and in adherence to the tribal sovereignty of the Wyandotte Nation. The project engages with diasporic perspectives, community-based pedagogy design, and tribally specific research protocols and policies. The living collective knowledgebase with which I engage in this …

Theses and Dissertations

In this dissertation study, I sought to identify the initial ideas that middle school students had when approaching Multiple Batches and Variable Parts proportion word problems, as well as the connections they made among those initial ideas. I conducted semi-structured individual and paired interviews with 13 sixth- and seventh-grade students at the end of their school year. I then used the Knowledge-in-Pieces theoretical perspective to identify knowledge resources that the participants accessed when approaching the tasks, prior to any intervention on my part.

Through my analysis, I identified 18 initial ideas that the middle school students employed when solving the …

Reconciliation, Draper Matthews

Theses and Dissertations

This thesis exhibition, Reconciliation, examines how memory, loss, and lived experience shape personal identity over time. Through sculptural works composed of cast, blown, and hot-sculpted glass combined with mixed media, the exhibition explores the pressures that life events place upon individuals and the ways those pressures persist, transform, and become integrated into the self. The work considers identity not as a fixed state but as a continual process of negotiation between past experiences, present circumstances, and future possibilities.

Central to the project is the material analogy between glass and human experience. Glass, a material formed under extreme heat and pressure …

The Effects Of A Work-Strengths Affirmation Intervention On Death Anxiety: Meaning And Self-Esteem As Mediators, Begüm Orhan

Theses and Dissertations

Death anxiety is a transdiagnostic construct and a universally experienced existential fear that has been linked to a wide range of psychological difficulties, including anxiety, depression, and impaired well-being. Despite its widespread impact, empirical research on targeted interventions for death anxiety remains limited. The present study aimed to address this gap by developing and evaluating an online, single-session, theory-based (i.e., Terror Management Theory, positive psychology) intervention focused on affirming personal strengths in the context of one's work. The intervention was designed to target work-strengths (i.e., leadership, adaptability)—an intersection of positive and vocational psychology.

Chitin is a biodegradable and biocompatible biopolymer with broad applications in the food, biomedical, pharmaceutical, and packaging industries. Conventional chitin production from crustacean shells is associated with seasonal availability, intensive chemical processing, and environmental concerns, creating interest in more sustainable alternatives. Filamentous fungi represent a promising source of chitin because of their rapid growth and ability to utilize low cost agro-industrial residues. This study evaluated the feasibility of producing fungal biomass and crude chitin from cheese whey through submerged fermentation while investigating the effects of whey type and enzymatic lactose hydrolysis on fungal growth, substrate utilization, and wastewater remediation. Aspergillus …

Peculiarities Of Phosphatidylserine Externalization By Nano- And Microsecond Electric Pulses, Mantas Silkunas, Alayna Enos, Iurii Semenov, Giedre Silkuniene, Eleni Zivla, Olga N. Pakhomova, Andrei G. Pakhomov

Bioelectrics Publications

Phosphatidylserine (PS) externalization is a hallmark of apoptosis but can also be triggered within seconds by pulsed electric fields (PEFs). Whether PS reaches the outer leaflet by lateral migration through electropores or indirectly through Ca²⁺-dependent signaling and scramblase activation remains debated. We used total internal reflection fluorescence (TIRF) microscopy with Annexin V-Alexa Fluor 568 and/or bovine lactadherin-FITC to resolve PS externalization in HEK293 cells placed on an indium tin oxide (ITO) transparent electrode. PEF exposures produced discrete PS-positive puncta ("freckles") within ~ 10 s after a 20-µs pulse (1.2-2.5 kV/cm) or with a ~ 1-min delay after a …

The Impacts Of Wing-Flashing By Northern Mockingbirds On Foraging, Parental Care, And Reproductive Success, Anna Reece Starman

Undergraduate Research Awards

Foraging efficiency may be enhanced by flashing patches of white wing and tail feathers and has been documented in several avian species. Northern Mockingbirds (Mimus polyglottos, NOMO) exhibit this “wing-flashing” (WF) behavior while foraging, during displays, and in response to predators. In NOMOs, WF has been hypothesized to increase foraging success, but previous findings are inconclusive. To further investigate the biological role(s) of WF behavior in NOMOs, the ventral surface of white primary feathers of male NOMOs were artificially darkened and the foraging and provisioning rates of undarkened (control) males and their mates were compared. While foraging, undarkened males performed …

Granulomatous Cellular Signatures In Nontuberculous And Tuberculous Mycobacterial Infections, Brianna M. Doratt, Ethan G. Napier, Mahdi Eskandarian Boroujeni, Sarah Douglas, Michael H. Davies, Luiz Bermudez, Eliot Spindel, Erin F. Mccaffrey, Ilhem Messaoudi

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Mycobacterium tuberculosis (Mtb) and nontuberculous mycobacteria (NTM) are acid-fast bacilli that trigger granuloma formation, a hallmark immune response aimed at containing infection. While the biology of Mtb granulomas has been widely investigated, far less is known about granulomas caused by NTM infection, despite the increasing prevalence and clinical challenge of NTM cases worldwide. Because granulomas influence infection control, pathology, and treatment response, understanding their cellular organization and signaling is critical to improving therapeutic strategies. Therefore, we characterized granulomas formed following infection of rhesus macaques with Mycobacterium avium subsp. hominissuis (MAH) and compared them to granulomas from cynomolgus macaques infected with …

Cocaine Upregulates Microglial Lipid Droplet Formation Through Increasing Lipid Synthesis Activity In Vitro And In Vivo, Yan Cheng, Brooke Russell, Liam Liyang Guo, Aryan Patel, Yan Y. Sanders, Ming-Lei Guo

Department of Biomedical and Translational Sciences Faculty Publications

A novel subtype of microglia, lipid droplet accumulation microglia (LDAMs), has been identified in the aged brain, which is characterized by sustained inflammation and senescent-like phenotypes. LDAMs are deeply involved in promoting brain aging as well as the pathogenesis of multiple neurodegenerative diseases. Cocaine can alter brain lipidomic profiles, induce microglial activation, and accelerate brain aging. This suggests that cocaine might affect microglial lipid metabolism, which ultimately aggravates aging-related neurological disorders in people with addictions. In this study, we explored the effects of cocaine on microglial lipid metabolism. Our results showed that chronic cocaine administration altered brain lipid profiles and …

False-Positive Detections In Avian Auditory Surveys: Effects Of Song Number And Directionality In A Calibration-Based Immersive Sound Environment, Katia Elena Chavez

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Detection-based surveys are widely conducted to monitor wildlife populations and provide data for estimating density and abundance. Avian count surveys are especially common because birds respond quickly to habitat degradation and restoration, making them effective indicator species. However, these detection-based surveys rely heavily on human observers and are prone to errors. If left unaddressed, these errors can bias estimates of species occurrence, and abundance, leading to misleading ecological inferences and management decisions. False-positive errors have received limited attention, in part because they are difficult to identify without independent confirmation of true species. To investigate false-positive rates in a controlled setting, …
