Federated Learning In The Era Of Foundation Models, Guangyu Sun

Graduate Studies Theses and Dissertations 2026

The emergence of large-scale foundation models has reshaped computer vision and multi-modal learning, but their substantial computational and communication demands pose significant challenges for deployment in federated learning (FL) systems. Federated learning enables collaborative model training across decentralized clients without sharing raw data, offering strong privacy guarantees. However, adapting foundation models in FL remains difficult due to communication bottlenecks, heterogeneous data distributions, limited device resources, and scarce labeled data. This dissertation presents a unified line of research that addresses these challenges through four complementary frameworks, progressively advancing the efficiency, personalization, and practicality of foundation model adaptation in federated settings.

Watch Your Step, Mind The Crowd: Socially Compliant Navigation In Unstructured Environments, Jack Vice

Graduate Studies Theses and Dissertations 2026

Autonomous mobile robots increasingly operate in complex real-world environments characterized by uneven terrain, dynamic obstacles, and human presence. This dissertation addresses the fundamental challenge of developing adaptive navigation strategies that enable robots to safely and effectively traverse unstructured outdoor environments including construction sites, agricultural fields, and disaster areas while maintaining social compliance around people. We advance this capability through five complementary contributions that collectively target dynamic, unstructured, human-occupied environments. First, we demonstrate evolutionary optimization of legged mobility for uneven terrain. Second, we propose using a spatiotemporal autoencoder to learn the temporal dynamics of moving people and objects. Third, we introduce …

Fgf19 As A Colorectal Cancer Serum Biomarker And Fgfr4 As A Mediator Of Anti-Her2 Resistance In Breast Cancer, Jordan Beardsley

Graduate Studies Theses and Dissertations 2026

The fibroblast growth factor 19 (FGF19)-fibroblast growth factor receptor 4 (FGFR4) signaling pathway regulates hepatic metabolism, bile acid (BA) synthesis, and hepatocyte proliferation. This signaling axis also is implicated in promoting tumor progression, therapeutic resistance, and metastasis in certain cancers.

In colorectal cancer (CRC) there is a critical need for non-invasive biomarkers for disease detection and monitoring. We identified FGF19 as a candidate CRC serum marker through meta-transcriptomics and found FGF19 to be expressed and secreted by CRC cell lines. Tumor-derived FGF19 was detectable in mouse serum at levels correlating with tumor volume in a subcutaneous xenograft model. RNA sequencing …

Exploring The Experiences Of Late Age-On-Arrival Multilingual Learners In Postsecondary Education, Robyn D. Ecklund

Graduate Studies Theses and Dissertations 2026

Multilingual learners (MLs) are the fastest growing population in the United States public school system (Biondi et al., 2024; Kanno & Cromley, 2013; Perez & Morrison, 2016; Varghese & Fuentes, 2020). Within this population of students, there is a subset of students that arrive in the United States during secondary school. These “late age-on-arrival” students face significant linguistic, cultural and social challenges in their pursuit of postsecondary success after high school (Kanno, 2021; Kanno & Cromley, 2013; Perez & Morrison, 2016). This interpretative phenomenological analysis sought to answer the research question: what are the lived experiences of late age-on-arrival MLs …

Investigating The Anti-Apoptotic Properties Of The N-Terminus Of The Chlamydia Trachomatis Effector Tarp, Kasey S. Jordan

Graduate Studies Theses and Dissertations 2026

As the most prevalent bacterial STI in the United States and leading cause of infection-related blindness worldwide, the obligate intracellular bacteria, Chlamydia trachomatis (Ct), poses a significant threat to public health. As an obligate intracellular bacteria, invasion of the host cell is a crucial step in Chlamydia’s developmental cycle. To drive invasion, Ct injects prepackaged effectors into the host cell using a T3SS. An early Chlamydial effector, translocated actin recruiting phosphoprotein, or Tarp, interacts with host cell actin to promote invasion, mediated via Tarp’s C-terminal region. Although the function of Tarp’s C-terminus is well defined, the Tarp’s N-terminus …

Investigating The Impact Of School Leaders’ Leadership Style And Teachers’ Intrinsic Motivation For Improved Science Instruction In Elementary Schools, Leila M. Greene

Graduate Studies Theses and Dissertations 2026

A report by the National Academies of Sciences, Engineering, and Medicine, determined that 69% of U.S. elementary teachers are not prepared to teach science, especially in the areas of earth/space and physical sciences. As a result, some elementary teachers avoid teaching science. School administrators play a key role in providing a supportive environment to inspire and motivate elementary science teachers. For this reason, the study utilized the Self-Determination Theory (SDT), to examine three types of school leadership styles (Transformational, Transactional, and Laissez-Faire) and how they impact the intrinsic motivation for elementary science teachers in three areas including autonomy, competency, and …

Contextual Influences On Algebra 1 Achievement In Florida: A Multilevel Analysis Of Fsa Data And Policy Implications For B.E.S.T., Alberto Leiro Jr

Graduate Studies Theses and Dissertations 2026

This study examined how school-level and district-level contextual factors are associated with Algebra 1 achievement in Florida using a multilevel modeling framework. Drawing on statewide publicly available data from the Florida Standards Assessments (FSA), the analysis included schools nested within districts to account for the hierarchical structure of educational data. School-level predictors included absenteeism, economic disadvantage, English language learner status, student mobility, and the proportion of students with disabilities, while district-level variables included poverty and crime rates. Results from the null model indicated that a meaningful proportion of variance in Algebra 1 achievement was attributable to differences among districts, supporting …

The study also examined principals' perceptions of culturally proficient leadership and principal preparation program attributes considered essential for leadership readiness in high-needs school settings. Guided by the Culturally Responsive School Leadership (CRSL) framework, data were collected through semi-structured interviews with 10 principals serving in urban Title I …

Evidence For A Spectral Break Or Curvature In The Spectrum Of Astrophysical Neutrinos From 5 Tev To 10 Pev, Karen Andeen

Physics Faculty Research and Publications

We report improved measurements of the all flavor astrophysical neutrino spectrum with IceCube by combining complementary neutrino samples in two independent analyses. Both analyses show evidence of a harder spectrum at energies below  ∼30  TeV compared to higher energies where the spectrum is well characterized by a power law. The spectrum is better described by a log parabola or a broken power law, the latter being the preferred model. Both, however, reject a single power law over an energy range 5 TeV–10 PeV with a significance  >4⁢𝜎, providing new constraints on properties of cosmic neutrino sources.

Black Hole Spectroscopy And Tests Of General Relativity With Gw250114, Jaclyn (Jax) Sanders

Physics Faculty Research and Publications

The binary black hole signal GW250114, the loudest gravitational wave detected to date, offers a unique opportunity to test Einstein’s general relativity (GR) in the high-velocity, strong-gravity regime and probe whether the remnant conforms to the Kerr metric. Upon perturbation, black holes emit a spectrum of damped sinusoids with specific, complex frequencies. Our analysis of the postmerger signal shows that at least two quasinormal modes are required to explain the data, with the most damped remaining statistically significant for about one cycle. We probe the remnant’s Kerr nature by constraining the spectroscopic pattern of the dominant quadrupolar (ℓ=m=2) …

Part 2: Divergent Paths? Rising Defense Spending And Headwinds For The Port And Tourism, Dragas Center For Economic Analysis And Policy, Old Dominion University

State of the Region Reports: Hampton Roads

The most recent economic data shows that the three-legged stool is tilting under the weight of conflicting economic policies. National defense spending has continued to expand, and we expect that, as a result, defense spending in Hampton Roads will also rise in the coming years. Declines in federal civilian employment will limit these gains, and the defense industrial base in the region faces an existential threat from the rise of uncrewed systems on the modern battlefield. The Port of Virginia performed well, gaining market share, but higher tariffs have negatively impacted the dollar volume of trade flowing through the Port. …

Likelihood-Based Inference For Random Networks With Changepoints, Daniel Cirkovic, Tiandong Wang, Xianyang Zhang

Mathematical and Statistical Science Faculty Research and Publications

Generative, temporal network models play an important role in analyzing the dependence structure and evolution patterns of complex networks. Due to the complicated nature of real network data, it is often naive to assume that the underlying data-generative mechanism itself is invariant with time. Such observation leads to the study of changepoints or sudden shifts in the distributional structure of the evolving network. In this paper, we propose a likelihood-based methodology to detect changepoints in undirected, affine preferential attachment networks where, upon introduction, a new node selects one old to attach to with probability proportional to its degree. In particular, …

Development Of In Vitro Hydrogel Blood Clots, Xiomara Garcia, Jasmine Urbina, Sapna Wolf

Bioengineering Senior Theses

Deep Vein Thrombosis (DVT) affects up to almost one million individuals in the United States annually and can lead to life-threatening complications, such as a pulmonary embolism. DVT occurs when a thrombus composed of platelets and fibrin forms within deep veins, obstructing blood flow. Current treatments include anticoagulants, thrombolytics, inferior vena cava filters, and balloon catheter procedures. However, the development and testing of these medical devices heavily rely on animal blood models due to physiological similarities in coagulation, raising ethical concerns and limitations related to cost, scalability, and sustainability. This project proposes a synthetic, in vitro alternative using agarose and …

The Role Of Adolescent Attachment In The Relationship Between Trauma And Identity, Ellie Mitova

Graduate Studies Theses and Dissertations 2026

Traumatic experiences have been shown to influence identity development during emerging adulthood, a complex developmental period. However, research examining how trauma interacts with adolescent attachment qualities to shape identity processes remains limited. Previous studies have primarily focused on infant attachment styles and their long-term developmental outcomes, leaving a gap in understanding how attachment qualities developed through relationships with parents and peers during adolescence may influence identity development in emerging adults. Additionally, while traumatic experiences have been associated with maladaptive identity processes such as rumination and identity distress, some research suggests that trauma may also contribute to deeper identity exploration and …

However, the legal and ethical issues within the transplantation industry are still of concern. Objective: We explore the opportunities and challenges for Organ Procurement Organizations (OPOs) to adopt AI. The US organ transplant system is a highly regulated industry yet open to innovation. Methods: Ten structured interviews were conducted with OPO representatives using the Extended Technology, Organization, Environment (TOE) framework. Results: Overall, we identified five core tensions in AI adoption: (1) misconceptions, (2) approach to training, …

Character Judgements Of Rap Music Fans, Kaila C. Putter, Dan J. Miller, Amy M. Belfi, James Rees, Amanda E. Krause

Psychological Science Faculty Research & Creative Works

Extending Fischoff, we used vignettes to examine people's perceptions of a hypothetical rap fan accused of murder. Study 1 (N = 300) used a 2 (murder accusation) x 2 (inclusion of rap lyrics) x 2 (fan gender) experiment, asking participants to judge how capable of murder and sexually aggressive they found the fan. The presentation of lyrics and murder accusation were associated with the fan being more capable of murder, while rap lyrics and participants' rap attitudes were associated with the fan being more sexually aggressive. Thematic analysis revealed that, in conditions containing both the lyrics and the murder accusation, …

When The Internet Attacks, Craig Cowie

Cardozo Law Review

Courts have struggled with applying personal jurisdiction in cases involving intentional torts where the defendants act outside the forum, and the problem is particularly apparent and acute when the defendants use the internet to commit the tort. For example, is there jurisdiction when a defendant doxxes someone and calls for violence? What if they leave a bad Yelp review? Or tweet a defamatory statement? Courts have used many tests for determining whether personal jurisdiction is appropriate in these situations, but there has been relatively little recent scholarship on whether these tests are appropriate for analyzing personal jurisdiction in these contexts. …

Much Ado About Misjoinder: An Alternative To Fraudulent Misjoinder To Preserve Defendants’ Right To Removal In Pharmaceutical And Medical Device Products Liability Cases, Alexander Flaum

Cardozo Law Review

Unresolved questions surrounding the contours of the fraudulent misjoinder doctrine have understandably led to reluctance by courts to adopt it, despite its utility in protecting defendants’ access to federal court. This is particularly troubling in the context of pharmaceutical and medical device products liability cases. It is common in these actions for plaintiffs, whose only connection is having consumed a particular pharmaceutical product at different points in time and for different durations, to strategically join in one action to defeat complete diversity and prevent removal to federal court. However, federal courts are not powerless to prevent such procedural gamesmanship. By …

Rivers Of Sovereignty: The Epa’S New Water Quality Standards Rule As A Potential Channel For Revitalizing Tribal Reserved Water Rights, Mostyn Josty

Cardozo Law Review

This Note explores the federal government’s evolving approach to its obligation to protect tribal reserved water rights through a case study of the Environmental Protection Agency’s (EPA) 2024 Water Quality Standards Regulatory Revisions to Protect Tribal Reserved Rights rule (the “WQS Rule”). It argues that while the WQS Rule represents a step forward in safeguarding tribal water rights, the legal challenge it faces underscores broader issues of federalism, administrative authority, and the country’s fluctuating commitment to tribal sovereignty. The Note examines the WQS Rule’s legal foundation, its potential challenges, and the implications for tribal self-determination, emphasizing the need for a …

Does The Internet Equalize Youth’S Civic Engagement? Examining Online And Offline Civic Engagement Among Adolescents And Young Adults, Yue Ni

Psychology Faculty Publications and Presentations

In this study, I examined disparities in online and offline civic engagement among 400 youth aged 15-25 years (Mage = 20.9; SD = 3.1) by subjective socioeconomic status (SES), race/ethnicity, and immigrant status. Results indicated that patterns of disparities in online civic engagement largely mirrored those observed offline. SES was the most consistent predictor: Youth who perceived their families as more well-off reported higher participation across both online and offline civic activities. In contrast, no significant differences were found between white youth and youth of color. Foreign-born youth reported higher levels of civic engagement in online and several …

The Ocean Is Not A Machine: A Feminist Media Analysis Of Oceanographic Models, Simulations, And Futures, Clarissa Chevalier

Study of Women, Gender, & Sexuality: Faculty Publications

This article examines how scientific and artistic representations and technologies shape ocean futures. Dominant Western oceanography frequently engages mechanistic metaphors that conceptualize the ocean as a machine, pump, or carbon sponge. This way of visualizing the ocean, guided by the logics of control and quantification, shapes contemporary remote sensing, modeling, and prediction technologies. Alternative approaches to oceanographic representation, including Indigenous, anticolonial, Black feminist, and artistic approaches, offer critical counterweights to destabilize the authority granted to mechanistic oceanographic representations. Ocean simulations and scale models are infrastructures through which ocean futures are rendered and presented in multidimensional space. Through a comparative media …
