High Impact Practices Student Showcase Spring 2025

As global temperatures rise due to climate change, tropical mangroves have spread poleward and now impact many other ecosystems, including salt marshes and oyster reefs in central Florida. A recent study documented a 198% increase in mangrove numbers on intertidal reefs of the eastern oyster (Crassostrea virginica) since 1984 in the Indian River Lagoon (IRL). Our field research project had two goals. First, to collect 2025 data as part of a long-term study to understand the current dimensions, densities, and spatial distributions of red mangroves (Rhizophora mangle) on intertidal oyster reefs in Mosquito Lagoon (north IRL), and second, to compare …

Damping Modulation Of Dampened Kapton Surfaces, Sebastian Esteban

Honors Undergraduate Theses

When droplets are vibrated or disturbed, they can exhibit a complex sloshing motion, an understudied behavior in drop physics. Droplet sloshing involves a complex combination of transverse and longitudinal motion that changes the droplet's effective weight on the surface the droplet is on. Our current understanding stems from preliminary work focusing on a cantilever beam of fixed thickness and variable viscosity of the liquid being sloshed. This investigation will focus on how variable cantilever thickness and constant viscosity for a liquid being sloshed affects the beam's deflection under consistent vibration. It will also investigate how the natural frequency of a …

Integrated Compliant Structure For A Hand Exoskeleton, Tristan R. Koopman

Honors Undergraduate Theses

This thesis presents the design and prototyping of a wearable hand exoskeleton that integrates a flexible structural framework to assist with hand movement while maintaining comfort and anatomical conformity. The goal was to create a device that supports tendon-driven actuation through a compliant structure, combining elements of rigidity and flexibility to match the natural geometry and motion of the human hand. Traditional hand exoskeletons often trade off motion for structure or vice versa. This project aims to bridge that gap with a hybrid compliant design that balances flexibility and support. The design process followed an iterative approach involving rapid prototyping …

Fabricating Silver-Ceria Polymer Nanocomposite Scaffolds For Biomedical Therapeutic Applications, Shreya S. Pawar

Honors Undergraduate Theses

Improper healing of bone fractures and limited regeneration of bone following bone tumor resection remain a prevalent complication worldwide. Long-term effects of this include joint instability, limited movement, and arthritis. Bone infections (osteomyelitis), reactive oxygen species (ROS) generation via excessive inflammation, and underlying conditions such as osteoporosis can contribute to suboptimal bone tissue regeneration. ROS accumulation stimulates osteoblast apoptosis, while promoting osteoclast differentiation. These processes inhibit mineralization and osteogenesis. Conventional therapeutics involve the utilization of drugs and bone grafts. However, these approaches pose limitations and can result in subsequent complications. Microbial infections, ROS accumulation, and excessive inflammations are factors that …

First, a microbial fuel cell (MFC)-based biosensor was developed for detecting heavy metals (Cu²⁺ and Hg²⁺) and PAHs (benzene and xylene). The system exhibited rapid, linear …

Multi-Trait Convergent Evolution Correlated With Host Ecology Suggests Trait Syndromes In Parasitoid Wasps (Hymenoptera: Braconidae)., Christina L. Watkins

Graduate Thesis and Dissertation post-2024

Convergent evolution, the independent evolution of similar traits in different lineages under shared ecological pressures, provides information on patterns of adaptation and character evolution. In Braconidae (Hymenoptera), a diverse and abundant parasitoid wasp family, the assorted biological and ecological traits of their insect hosts have been frequently hypothesized to drive repeated morphological evolution. This study presented the first family-wide phylogenetically informed test of host-driven convergence in Braconidae, integrating morphological and ecological data across 74 genera representing 32 subfamilies on the most current and robust phylogeny. Analyses revealed multiple instances of correlated evolution between host traits and parasitoid morphology, suggesting trait …

An Ailment I Will Fight With: Differential Diagnosis And Methodology Evaluation Of Possible Treponemal Infection At Dayr Al-Barsha, Egypt, Lindsey D. Lefebvre

Graduate Thesis and Dissertation post-2024

Treponemal diseases, including bejel, yaws, pinta, and venereal syphilis, have long plagued human populations and continue to pose public health challenges today. Despite their persistent global presence, the origins, transmission pathways, and archaeological identification of these diseases—caused by various subspecies of Treponema pallidum—remain contested. This study explores the utility of standardized diagnostic criteria, as proposed by Baker et al. (2020), in assessing the presence of treponemal disease in highly fragmentary skeletal remains from the Roman-period necropolis at Dayr al Barsha, Egypt. Through the examination of 14 individuals, this research seeks to (1) identify indicators consistent with bejel (T.p. …

Investigating The Impacts Of Peer Support And Online Information Seeking In Chronic Pain Online Health Communities, Aaron Necaise

Graduate Thesis and Dissertation post-2024

Chronic pain is a highly prevalent medical condition that contributes to intense emotional distress and social isolation in patients. With the growth of social media, online health communities (OHCs) have become a popular resource for patients to learn about their pain and establish social connections with peers. Although there is some evidence suggesting that curated online resources can benefit patient well-being, social media interactions have the potential to propagate medical misinformation and negativity. This dissertation expands upon the Social Communication Model of Pain to examine how interactions within social media-based OHCs impact chronic pain and uncover practical insights into OHC …

This dissertation integrates whole-genome sequencing and immunogenetics to assess the genomic consequences of habitat fragmentation across three primary Florida Scrub-Jay strongholds: Archbold Biological Station, Ocala National Forest, and Florida’s East Coast. In Chapter 2, I focused on adaptive genetic diversity at the Major Histocompatibility Complex (MHC) class II genes. I characterized MHC allelic richness, evaluated signatures of selection, and examined associations with pathogen infections. Despite population declines, I found moderate MHC diversity, suggesting …

Contagion Chronicles: A Spatiotemporal Analysis Of Armed Conflict And Infectious Disease, Devyn Escalanti

Graduate Thesis and Dissertation post-2024

This dissertation examines the relationship between armed conflict and infectious disease transmission through a novel theoretical framework that integrates ecological disturbance and health systems resilience theories into epidemiological contexts. The framework conceptualizes diseases along a continuum from "pulse" to "press." Pulse diseases, like Ebola, are characterized by sudden onset, high mortality, and short-term outbreaks. Press diseases, like HIV, progress gradually with lower mortality and long-term persistence. Grounded in this pulse–press disease typology and ecological and health systems resilience, the theory suggests that the absorptive capacity, adaptive capacity, and resilience of community health workers in conflict areas can influence disease transmission, …

This research investigates the doping of cerium oxide with silver (Ag) and its correlation with the properties of the material. Silver-doped cerium oxide nanoparticles were synthesized by wet-chemical synthesis at room temperature by a facile procedure. Cerium oxide was doped with …

Gait Kinematics And Muscular Responses To Rhythmic Perturbations In Healthy Young Adults, Kayley A. Romero

Graduate Thesis and Dissertation post-2024

Falls pose a significant risk across all ages, leading to injury and loss of independence. Understanding gait adaptation to external perturbations provides insights into balance control and muscle activation, with implications for rehabilitation and fall prevention. While entrainment, the synchronization of biological rhythms to external stimuli, has been widely studied using auditory and visual cues, its effects in response to mechanical perturbations remain unclear. This study examines how young, healthy adults adapt to discrete mediolateral perturbations and whether entrainment occurs when mediolateral perturbations are applied at set timings determined by their natural stride period.

However, this network is inherently vulnerable to cyberattacks. This dissertation presents a hybrid methodology to model and analyze the dynamic behavior of an electrical Smart …

Shock Tube Droplet Breakup Experiments Facilitated By Acoustic Levitation, Anthony J. Aguilera

Graduate Thesis and Dissertation post-2024

Droplet introduction methodology in a shock tube differs based on the experimental conditions. For experiments in which the objective is to image droplet breakup, acoustic levitation allows for a consistent droplet shape and for diagnostic equipment to be aligned to a droplet prior to an experiment. A levitator was designed and used in the University of Central Florida’s shock tube facility. Polystyrene doped droplets were levitated to increase the likelihood of cavitation occurring. Multiple droplets were impacted by a shock wave, and the breakup regime was captured using a high-speed camera.

Paleoethnobotany And Starch Grain Residue Analysis Collected From Ceramics At The White Marl Site, Jamaica, Lydia E. Kiernicki

Large Language Models And Networks: Edge Proposal, Synthetic Corpora, And Adaptive Node Generation, Nathan Gonzalez

Graduate Thesis and Dissertation post-2024

Natural Language Processing (NLP) and Artificial Intelligence (AI) have evolved from brittle rule-based engines through data-driven statistical models to today’s transformer architectures whose multi-head attention enables rich contextual reasoning. Against this backdrop, this dissertation unifies three complementary investigations that deepen our understanding of how large language models (LLMs) can reason over, generate, and strategically adapt language within networked settings. First, instruction-tuned LLMs are recast as latent-relationship detectors: by prompting models to hypothesize links between text-described entities, we recover edge sets that reconstruct social, thematic, and citation graphs with high precision, revealing how attention distributions encode topological cues. Recognizing the difficulty …

Multivariate correlation, principal component analysis, and multiple regression were employed to determine dominant drivers of toxin occurrence. …

Exploring The Genetic Structure And Evolutionary History Of Marine Fish Populations Across Micronesia, Pavithiran Amirthalingam

Graduate Thesis and Dissertation post-2024

Most marine species exist as metapopulations, composed of subpopulations inhabiting patchily distributed habitat. Connectivity among these subpopulations is primarily facilitated by larval dispersal via ocean currents. Understanding patterns of population connectivity is crucial for evaluating metapopulation dynamics and ensuring long-term population stability in managed species. Micronesia, a vast region in the North Pacific with hundreds of islands, is the northern extent for many tropical species and is thought to function as vital stepping-stones between the central and western Pacific. However, limited phylogeographic studies in the region have left significant knowledge gaps regarding metapopulation dynamics. Here I address this knowledge gap …

Characterizing Muscle Control As An Emg Visual Matrix, Peter W. Makary

Graduate Thesis and Dissertation post-2024

Evaluating electrical muscle activity patterns using surface electromyography (EMG) is a widely used technique to assess movement in research settings, but its use has not been translated to clinical settings. This study aims to investigate the potential of evaluating muscle activity control through a visual matrix display. EMG data from older and younger adults collected in a previous seated locomotor perturbation study was used to generate visual matrices representing their lower-limb ankle muscle activity. Visual matrices from each condition consist of 20x20 grids, where each axis represents activity from an individual muscle of muscle pairs, such as the tibialis anterior …

‘Who’S Your Daddy?’: Ddradseq Parentage In Broodstock-Offspring Pairs Of Diadema Antillarum In A Population Restoration Initiative, Bianca R. Rosendahl

Undergraduate Scholarship and Creative Works

In the early 1980s Diadema antillarum, or the long-spined urchin, was hit by a catastrophic mass mortality event across the western Atlantic and Gulf of Mexico, inclusive of the Florida Keys. The cause of this die-off event was likely triggered by a pathogen or environmental stressor that decimated native populations by up to 98%. The species has not yet fully recovered and is struggling with recruitment success which is why it may benefit from an ex-situ recovery program. In this study, I used single nucleotide polymorphisms (SNPs) to identify genetic variation and analyze parentage in a captive population of …

A New Dawn Of Joy: How Joy Is Cultivated Among Black Transgender And Nonbinary Young Adults In Florida, Courtney Marciá Gardner

Graduate Thesis and Dissertation post-2024

The state of Florida had a record-breaking number of implemented and proposed policies between 2023-2024 that impacted transgender and nonbinary individuals. Black transgender and nonbinary people are particularly impacted by these policies due to the compounded effects of their race and gender identity. Nonetheless, despite the growing literature on Black transgender and nonbinary individuals, a lack of research exists examining positive aspects of intersectional experiences among Black transgender and nonbinary individuals. This qualitative study shifts away from deficit centered frameworks by investigating how Black transgender and nonbinary young adults in Florida cultivate joy in their lives. This study uses a …

A Mathematical Modeling Approach To Investigate The Impacts Of Post-Infection Mortality And Partial Immunity On Disease Endemicity, Brendan M. Shrader

Honors Undergraduate Theses

A number of infectious diseases cause post-infection conditions or complications, such as COVID- 19, Q fever, and Polio. These conditions result in recovered individuals having a higher mortality rate than susceptibles, and this can impact disease dynamics. An existing mass-action model in the literature that incorporated post-infection mortality was shown to have limit cycles, or persistent oscillations, in the infected population. To better understand what causes these limit cycles, we develop and analyze a new epidemiological model with standard incidence. We show standard results, including the existence, uniqueness, and stability of the disease-free and endemic equilibria, and we rule out …

The Association Between Pain Sensitivity And Low Energy Availability, Sleep, Mental Health, And Stress In Female Endurance Athletes, Taylor R. Moler
