Attentional Control, Anxiety, And Depression, Anna Morgan

2026 Research Poster Competition

Anxiety and depression are among the most prevalent and debilitating mental health conditions worldwide. Research suggests that both anxiety and depression are related to deficits in the ability to focus and shift attention, known as attentional control. These effects are present in data using behavioral measures of attentional control (e.g., accuracy in resequencing alphanumeric strings) and self-report measures, though more strongly in the latter. However, studies have found little if any correlation between behavioral and self-report measures of attentional control. One possibility is that anxiety and depression are associated not only with deficits in attentional control, but also more strongly …

Social Isolation Predicts Altered Reward Circuit Connectivity And Future Behaviors In Adolescents, Mason Lucas

2026 Research Poster Competition

Adolescence is a period of transition from childhood to adulthood when people explore risky behaviors. Stressors during adolescence can change structural brain connectivity. Previous research has found weaker structural connectivity between reward circuits and future cognitive impairments among children raised in orphanages. Comparative research in mice suggests that social isolation after bullying can damage these connections and induce alcohol seeking. We tested whether social isolation was related to lower connectivity of targeted structural connections in adolescent humans. We analyzed data from the Adolescent Brain Cognitive Development study and found 130 subjects had experienced extreme social isolation. To evaluate the level …

From Chaos To Clockwork: Investigating The Role Of Circadian Genes In Metabolic Development Of 2nd And 3rd Instar Drosophila Larvae, Elliott Ruegsegger

2026 Research Poster Competition

Connecting deficits in circadian rhythm machinery to the severity of other health conditions is a common task that chronobiology, the study of physiological rhythms, undertakes. Disruptions to circadian rhythms and sleep are linked to increased risk of developing multiple different diseases, including Alzheimer’s Disease and obesity. Circadian rhythms are expressed at the molecular level through rhythmic variations in the concentration of specific proteins. While the central clock genes that produce these proteins, such as period and timeless, are evolutionarily conserved across the animal kingdom, not much is known about the consequences of disruptions in circadian rhythm machinery during early development, …

Assessing Mesenchymal Stem Cell Phenotype After Heparan Sulfate Supplementation, Isani Patel

2026 Research Poster Competition

Multiple sclerosis is an autoimmune disease that damages the protective coating of nerves, often causing lasting neurological symptoms. Current treatments slow disease activity but rarely repair existing damage. In response to this, a novel treatment option has emerged: mesenchymal stem cell (MSC) therapy. MSCs are cells found in different adult tissues like bone marrow, and they have the potential to release repair-supporting signals and moderate inflammation. Nevertheless, results in a clinical setting have been inconsistent due to variations in cell potency. As a potential strategy to enhance MSC therapeutic potential, the addition of heparan sulfate, a naturally occurring signaling molecule, …

Investigating Changes In White Blood Cell Composition In Wild Hosts In Response To Viral Infection, Anna Bolding

2026 Research Poster Competition

Reservoir hosts play a critical role in the persistence and spillover of zoonotic pathogens. Upon infection, reservoir hosts can shed viral loads sufficient for transmission and spillover often without displaying apparent pathogenic effects. Investigating how their immune systems control infection can provide insights into the factors that facilitate spillover events. Understanding the mechanisms that enable these infection characteristics is crucial for informing public health and conservation strategies. Though reservoir hosts’ immune responses are well-documented in controlled laboratory settings, these studies are not representative of natural populations. The bank vole - Puumala hantavirus (PUUV) system is well suited for investigating such …

Temporal Variational Graph Autoencoder For Influenza Evolution, Soumya Chauhan

2026 Research Poster Competition

Frequent mutations in influenza virus surface proteins can increase infectivity while evading human and vaccine immunity, causing seasonal epidemics. The CDC annually evaluates thousands of virus strains to predict mutated sequences likely to be dominant in the next season, which creates a need for methods that better capture how viral mutations evolve over time. In this study, we represent influenza protein sequences as a network-like graph, creating connections if sequences are collected a week apart and only differ by one mutation. This method explicitly considers time information as part of the evolution, while other existing methods analyze mutated sequences without …

Investigating The Potential Role Of Horse Flies (Diptera: Tabanidae) In The Mechanical Transmission Of Anaplasma Marginale And Theileria Orientalis To Cattle In Northwest Arkansas, Catherine Harrison

2026 Research Poster Competition

The cattle industry in Arkansas plays a significant role in the state’s agricultural economy; however, two emerging infectious diseases pose a threat to cattle health, producer livelihood, and animal welfare. The two diseases, anaplasmosis and theileriosis, are caused by organisms that enter the host’s bloodstream and infect red blood cells, leading to destruction of said cells. The shared symptoms of both diseases are fever, weakness, anemia (low red blood cell count), reduced productivity, weight loss, and possibly death. An important difference between symptoms is that, unlike anaplasmosis, theileriosis can cause abortion in cattle. Both diseases are known to spread through …

Cardiovascular Monitoring For Maternal Health Using Wearable Devices, Daniela Alejandra Vasquez

2026 Research Poster Competition

Cardiovascular disease represents the leading cause of pregnancy-related mortality in the United States, accounting for over 30% of maternal deaths, with preeclampsia and hypertensive disorders contributing significantly to this burden. In Arkansas, maternal mortality rates reach 41.9 deaths per 100,000 live births. Current prenatal care relies on intermittent office-based blood pressure measurements conducted during 12-14 clinical visits, may not capture critical cardiovascular changes in a timely manner. Preeclampsia is characterized by new-onset hypertension after 20 weeks of gestation, affects 3-7% of pregnancies, and requires early detection to enable timely intervention. The limited accessibility of ambulatory blood pressure monitoring in rural …

Predictors Of Stigma And Their Relation To Mental Health Help-Seeking Attitude In College Students, Esiquil Lara

A Bayesian Late-Fusion Supportability Framework For Rare-Disease Severity Prediction In Glut1 Deficiency Syndrome, Jordan M. Rodriguez

Mathematics Dissertations

Glucose transporter type 1 deficiency syndrome (GLUT1-DS) is a rare neurometabolic disorder with heterogeneous neurological and developmental severity. Because patient-level severity is not observed as a single validated outcome, this dissertation develops a Bayesian late-fusion supportability framework for constructing and predicting an ordered latent severity phenotype from clinical, genetic, and EEG-derived evidence. The primary target was constructed in a larger clinical cohort using age-5 symptom burden and learning cognition, then assigned to an aligned multimodal prediction cohort. Target-defining variables were excluded from supervised predictors, and models were evaluated using patient-exclusive cross-validation with training-fold preprocessing and fold-wise EEG PCA.

The primary …

Blood Flow Regulates Metabolism In Hematopoietic Development, Pamela L Wenzel

Faculty, Staff and Student Publications

Blood flow modifies oxygen availability and biomechanical forces within the vasculature of the embryo as the hematopoietic system develops. The aorta-gonad-mesonephros (AGM) envelops the largest artery in the body and is a critical site for the emergence of hematopoietic stem cells (HSCs). Herein, I discuss the role of hypoxia-inducible factors (HIFs) and force as determinants of metabolism and fate determination. To address the effects of blood flow on hematopoietic development, I employ mouse embryo models and biomimetic culture. Real-time cell metabolic analyses show that oxygen consumption rates (OCR) and extracellular acidification rates (ECAR) are altered by flow in cultures of …
