Phishing Restraint: University Simulated Phishing Campaigns, Alexander M. Abou Khir

Cybersecurity Undergraduate Research Showcase

Universities face heightened vulnerability to phishing attacks due to their open information-sharing culture and diverse user populations. This study examines how phishing exploits human factors within campus environments and evaluates three major training strategies: embedded phishing, microlearning, and role-based instruction to understand their individual and combined effectiveness. I explored studies that implement these strategies in pairs and use the strategies alone, identified trends in susceptibility reduction, behavioral reinforcement, and contextual relevance. I suggest that, while each method independently improves user awareness, multiple approaches offer stronger, more adaptable protection by addressing both psychological triggers and role-specific risks. The paper contributes a …

Salivary Mirna As An Early Biomarker For Oral Squamous Cell Carcinoma, Shloka Potineni

Student Publications and Research

Oral squamous cell carcinoma (OSCC) is diagnosed at late stages in the majority of cases despite its physically accessible location, resulting in five-year survival rates that drop from 90% at Stage I to below 50% at Stage III or IV. Current screening relies on visual examination and invasive biopsy, neither of which can detect the molecular changes that precede visible tumor formation. MicroRNAs (miRNAs) in saliva reflect tumor biology before lesions appear, but the signal spans over 2,000 species simultaneously, making traditional statistical methods insufficient for reliable diagnostic pattern extraction.

This study applies a Random Forest classifier to miRNA expression …

Post-Operative Delirium: A Neurocognitive Syndrome Expressed Through An Interactive Website Module Of Animations, Bailey Mikytuck

Theses

Post-operative delirium (POD) is a neurocognitive complication that can arise in patients who have undergone a surgical procedure. It is characterized by the onset of reduced attention or cognition, mood or personality disturbances, and hallucinations that occur between 10 minutes to multiple days after waking up from anesthesia. These symptoms may only be brief, but in some cases can lead to long-term cognitive impairment and dysfunction and have been associated with the development of dementias. It is estimated that rates of POD occurrence are between 13.2- 41.7% with major risk factors including being over the age of 65 and the …

Flu Vaccine Hesitancy In College-Aged People, Maria Sadek, Dr. Kaitlin Bonner

Fisher Showcase 2026

This project investigates influenza vaccine hesitancy among college‑aged individuals, the age group with the lowest national vaccination rates, to determine how these patterns manifest at Fisher. Building on my previous semester’s literature search, this semester focused on a deeper review of documented barriers and the development of an IRB‑approved survey tailored to Fisher students. Prior research highlights several predictors of vaccination, including past flu experience (a very strong predictor of vaccination behavior) and encouragement from trusted authorities. Alternatively, common barriers include low perceived risk, safety concerns, and cost or time constraints. Fisher‑specific data were collected to assess whether these national …

The Genetics Of Sex, Fortis Brown

The Agora

Sex is a complex biological process that begins in the womb and lasts into puberty and beyond. It is often presented to society as a binary, chromosome-based system where XX means female and XY means male. In reality, chromosomes are just the beginning of a lifelong process involving hormones that influence biological changes. This process becomes apparent with its errors, known as Differences in Sexual Development (DSDs). DSDs can be caused in two main ways: through changes in either meiosis or in gene expression. While many consider these changes as ‘errors’, the processes that cause them to have been intentionally …

Nutrition Strategies To Help Children With Arfid Overcome Nutrition-Related Deficiencies, Saul Campos

The Agora

Avoidant/Restrictive Food Intake Disorder (ARFID) is a serious and relatively newly recognized eating disorder that affects children and adolescents. The disorder was formally introduced in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) and is characterized by restrictive eating patterns that lead to significant nutritional deficiencies, weight loss or poor growth, dependence on nutritional supplements, or interference with psychosocial functioning (American Psychiatric Association, 2013). Current estimates suggest that ARFID may affect approximately 1–5% of children and adolescents, though prevalence varies depending on the population studied and diagnostic criteria used (Białek-Dratwa et al., 2022). Unlike other eating disorders, …

Exploration Of A Relationship Between The Activities Of Trail And 4’-Trifluoromethoxychalcone., Abigail C. Ernst

Undergraduate Theses

Cancer is the overgrowth of dysregulated or mutated cells that affects 1 in 3 Americans. Chalcones are natural products with many possible derivatives, such as 4’-trifluromethoxychalcone (4TF), developed in Dr. Krzysiak’s lab, which exhibit anticancer activity against cancer cell lines. Tumor Necrosis Factor-Related Apoptosis-Inducing Ligand (TRAIL) is a tumor surveillance cytokine that acts on two receptor types: death receptors and decoy receptors. One way cancer cells can become resistant to TRAIL is by upregulating decoy receptors and/or downregulating death receptors. In this study, MTS assays evaluated the potential relationship between TRAIL and 4TF that sensitizes A549 cells to TRAIL. The …

Inside Looking Out The Joslyn Museum Geoportal Field Guide, Harmon D. Maher Jr.

Geography and Geology Faculty Publications

Inside Looking Out: The Joslyn Museum Geoportal Field Guide presents the Joslyn Museum as a unique interdisciplinary space where art and geology intersect. The guide invites readers to explore the museum not only through its paintings but also through its architectural materials, treating both as “portals” into broader narratives of Earth’s history, landscapes, and human experience. Organized as a series of flexible “field sites,” the book examines artworks and building stones side by side, highlighting how geological processes—such as sedimentation, metamorphism, and erosion—inform both the physical structure of the museum and the imagery within its collections. By blending scientific inquiry …

Identification Of Sex Chromosomes In The Genus Lepidodactylus, Zuleihat Yusuf Idris

Master's Theses (2009 -)

ABSTRACT IDENTIFICATION OF SEX CHROMOSOMES IN THE GENUS LEPIDODACTYLUS Zuleihat Y. Idris, M.S Marquette University, 2026 Sex determination in vertebrates is remarkably diverse and is characterized by frequent evolutionary transitions between genetic sex determination (GSD) and environmental sex determination (ESD). Within reptiles, geckos (Gekkota) exhibit the most diverse sex determination mechanism in vertebrates. Although geckos are the target of more recent research, most lineages still lack identifiable sex-determining mechanisms. This gap in knowledge has limited the understanding of the diversity and evolution of sex determination in vertebrates. In this study, an automated pipeline (FnPiPER) and whole-genome resequencing from male and …

Agentic Hallucination Risk Scoring For Medical Llms Via Uncertainty Quantification And Clinical Knowledge Injection, Mayank Kapadia, Mohammad Masum

Faculty Research, Scholarly, and Creative Activity

Large Language Models (LLMs) have witnessed significant adoption across numerous domains since 2020, but their proclivity to hallucinate creates unacceptable dangers in high-risk environments like healthcare, where wrong outputs can directly jeopardize human safety. While present systems focus on pre-generation mitigation strategies, they cannot ensure the safety of individual outputs during inference. We provide a post hoc Hallucination Risk Scoring (HRS) methodology that intercepts questionable outputs before they reach patients via an agentic pipeline. Given a medical question, a domain-specific LLM generates an initial response from which five complimentary uncertainty signals are computed, which are then separated into a decision …

Metonymy In Sound: A Neurolinguistic Study Of Al-Mullalah Soundscape Using Fnirs, Rand Naser Muflih

Theses and Dissertations

This thesis offers an interdisciplinary exploration of the semantic and neurolinguistic development of Al-Mullalah, a traditional Palestinian "coded" song type. By combining metonymy, soundscape analysis, and functional neuroimaging, the study traces the evolution of Al-Mullalah from a localized, covert means of communication tied to historical struggle to a globally recognized auditory symbol of collective resilience. The research uses a multi-method approach. First, soundscape analysis demonstrates how Al-Mullalah functions within Palestinian aural counterpublics, strengthening communal memory through various uses. Second, a qualitative analysis of semantics and themes examines how the text's metonymic structures change over time. Lastly, a Functional Near-Infrared Spectroscopy …

Tracing Microplastics From Polymer-Coated Urea: Urban To Agricultural Pathways And Environmental Fate, Caden Joseph Seely

Theses and Dissertations

Polymer-coated urea (PCU) is widely used as a slow-release nitrogen (N) fertilizer because it improves N use efficiency and reduces losses through leaching, denitrification, and volatilization. However, the polymer coating raises concerns about potential microplastic (MP) transport to surface waters following fertilizer application. This thesis evaluates the off-site transport of MPs and associated nutrient and sediment losses from PCU in both urban landscape and agricultural systems. In the urban landscape study, treatments included sod, mulched beds, and water-efficient ground cover receiving uncoated urea, PCU, or liquid slow-release N at 225 kg N ha⁻¹ (with reduced rates for beds and ground …

Ms-Gator: Multi-Scale Graph Attention With Topological Reasoning For Segmentation And Classification Of Prostate Cancer Based On Gleason Scores Using Histopathology Images, Sujata Patil, Mahadeva Swamy, Kavitha Sooda, Rajanikanth Vadigepalli, Khalid Nazim Abdul Sattar, Md Rafeeq

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Prostate cancer is one of the prevalent and potentially fatal malignancies, affecting men globally. Accurate segmentation and classification of prostate cancer in histopathology images remain challenging due to complex tissue architecture, staining variability, and high inter-observer differences in manual diagnosis. To address these challenges, this research proposes a Multi-Scale Graph Attention with Topological Reasoning (MS-GATOR) for segmentation and classification of prostate cancer based on Gleason Scores (GS). The MS-GATOR incorporates topological reasoning with hierarchical biological structures by constructing a graph-based representation among three spatial scales such as nuclei, glands, and tissues using Delaunay triangulation to capture both geometric and photometric …

Developmental Underpinnings Of The Other Race Effect Using Fmri, Aquilla Denise Copeland

Electronic Theses and Dissertations

It is well established that perceptual experience with own-race faces is associated with faster and more accurate recognition of own-race compared to other-race faces — a phenomenon known as the other-race effect (ORE). Previous fMRI research has shown that adults generally exhibit more robust face-sensitive responses than children in the core face-processing areas, especially to own-race versus other-race faces. Although much is known about the neural underpinnings of the ORE in adults, little is known about this phenomenon in children. The present experiment aimed to examine face-sensitive fusiform and occipital regions in 8- to 10-year-olds and adults as they engaged …

A Computer Vision Approach To Analyzing Taxane Effects On Prostate Cancer Cells, Diana Elizabeth Dancea

Electronic Theses and Dissertations

Actin is a family of proteins that help create the structure of the cytoskeleton, which gives shape to the cell. In many chemotherapy treatments, researchers target actin because it controls the cell division process. Therefore, if they are able to understand the actin fibers, that may help in formulating methods to stop or slow down cancer cells from reproducing. Another important protein is PAK6, which regulates actin. In our research, a collaborative effort with Prof. Michael Lu’s lab at Florida Atlantic University, we use machine learning techniques to analyze cells which had their PAK6 protein knocked out, and compare them …

The Fungus Among Us: Latency, Reactivation, And The Expanding Clinical Spectrum Of Coccidioidomycosis, Sumeet Bhardwaj, Arushi Tewari, Rishima Tewari, Simona Kogan

Student Publications

Coccidioidomycosis is a serious fungal infection that can produce a wide range of clinical manifestations, from mild, self-limiting pulmonary disease to severe, disseminated infection that can involve nearly any organ system, including the skin. Coccidioidomycosis may also affect patients at the psychiatric level. Its clinical relevance has increased markedly in recent years, as incidence continues to climb, geographic distribution widens, and emerging presentations challenge traditional assumptions regarding fungal latency and host immunity. A notably important and developing area of study is the concept of late reactivation. A narrative review of the literature was conducted using PubMed, MEDLINE, and Google Scholar. …

Conserved Post-Odor Dynamics In The Olfactory Systems Of Mice And Locusts, Elizabeth H Moss, Doris Ling, Cameron L Smith, Feiyang Deng, Ryan Kroeger, Jacob Reimer, Baranidharan Raman, Benjamin R Arenkiel

Faculty, Staff and Students Publications

Interpreting chemical information and translating it into ethologically relevant output is a shared challenge of olfactory systems across species, but are olfactory computations conserved across species to overcome these common challenges? To investigate this, we compared neural activity in the locust antennal lobe (AL) and mouse olfactory bulb (OB) both during and after odor presentations. We found that odors activated nearly mutually exclusive neural ensembles during odor presentations ("ON response") and after the termination of the odor stimulus ("OFF response"). ON and OFF responses evoked by a single odor were anticorrelated with each other. Inverted OFF responses persisted long after …

An Emerging Approach To Ibd Treatment: Personalized Nutrition Through Gut Microbiome Optimization., Kafayat Yusuf, Thomas M. Attard, Mazin Al-Kasspooles, Shahid Umar

Manuscripts, Articles, Book Chapters and Other Papers

Inflammatory bowel disease (IBD) is a chronic inflammatory disorder of the gastrointestinal tract characterized by relapsing and remitting disease activity. Despite decades of research, a definitive cure for IBD remains elusive, as cycles of remission and flare-ups mark the disease course and often relies on long-term pharmacologic and supportive strategies. Increasing evidence indicates that diet and nutrition play an important role in modulating the outcomes of IBD. Although a wide range of dietary interventions has been explored, no universally effective approach has been established. Investigations have also proven that different dietary interventions can significantly affect clinical outcomes by altering gut …

Vascular Burden Attenuates The Tdp-43-Tmem106b Pathological Relationship In Neurodegenerative Disease With And Without Alzheimer Disease Neuropathological Change, Matthew B. Dopler, Cole Corbett, Angelique D. Gonzalez, Ali Ghaseminejad-Bandpey, Mallory Keating, Kyra M. Clarke, Oluwaseun B. Ogunbona, Gladys Maestre, Sudha Seshadri, Shahroo Etemadmoghadam, Margaret E. Flanagan

TMEM106B, a lysosomal transmembrane protein, is a risk factor for neurodegenerative diseases, including Alzheimer disease (ad) and TDP-43 proteinopathies. TMEM106B pathology occurs in normal aging and is increased in TDP-43 proteinopathy but its role in dementia remains unclear. Cerebrovascular disease (CVD) is a driver and co-pathology of dementia, yet its contribution to TMEM106B accumulation in the context of TDP-43 and ad neuropathological changes (ADNC) has not been explored. We analyzed post-mortem human hippocampal sections spanning not-, low-, intermediate-, and high-ADNC. In secondary analyses, cases ≥65 years were stratified by TDP-43 immunopositivity and CVD severity; cases < 65 years were included to contextualize age-associated effects. TMEM106B immunoreactivity was quantified using digital pathology. Linear regression models demonstrated that age and sex (higher in females) were independent predictors of TMEM106B immunopositivity whereas Braak stage, CERAD-NP score, and Thal phase were not. The positive TDP-43-TMEM106B association was attenuated with increased CVD pathology severity, suggesting that vascular burden modifies this relationship. Sensitivity analyses restricted to LATE-NC attenuated several associations, indicating that pooled TDP-43 findings should be interpreted cautiously given possible disease heterogeneity. TMEM106B immunoreactivity was most strongly associated with age and sex, while vascular burden, rather than ADNC level, modified its relationship with TDP-43 proteinopathy.

BACKGROUND AND OBJECTIVES: The prospective single-arm nonrandomized SCENT (Surpass Intracranial Aneurysm Embolization System Pivotal) trial on flow diverter treatment of large and giant intracranial aneurysms (IA) was analyzed for patients' age and IA characteristics affecting stroke and occlusion rates over 5 years (Trial registration NCT01716117).

METHODS: Impact on major ipsilateral stroke and IA occlusion was studied by stratifying age as 65 years and younger vs older than 65. Kaplan-Meier estimates of time to both endpoints, stratified by age, were created. Univariate predictors of time-to-stroke were analyzed using univariable proportional hazards regression models. Limited bivariable modeling was also attempted.

Analyzing Label Structure And Regional Similarity In Watershed Data Via Spectral Clustering, Yifan Luo

25th Annual A. Paul and Carol C. Schaap Celebration of Undergraduate Research and Creative Activity (2026)

This project focuses on identifying patterns of seasonal transitions and nutrient salt fluctuations within the watershed environment. To capture the complex relationships between multiple sampling sites and environmental variables, we represent the watershed dataset as a weighted graph, where nodes correspond to water samples and edge weights reflect similarity in environmental conditions or nutrient concentrations. Using the Gaussian kernel function, we encode the connectivity structure of this network and quantify how similar different nodes are. We then perform spectral embedding by projecting the high-dimensional graph into a lower-dimensional space using the eigenvectors of the Laplacian matrix. This approach preserves the …

Temporal Interference Stimulation Effectively Reduces Parkinsonian Beta Band Activity In A Computational Model Of The Basal Ganglia Network, Anna Stolle

25th Annual A. Paul and Carol C. Schaap Celebration of Undergraduate Research and Creative Activity (2026)

Parkinson’s disease (PD) is a progressive neurological disorder characterized by degeneration of dopaminergic neurons, leading to impaired motor function and disrupted basal ganglia activity. One of the most effective treatments is deep brain stimulation (DBS), which targets deep brain regions to restore abnormal firing patterns. However, DBS requires invasive surgery to implant electrodes, posing surgical risks and limiting accessibility. This has driven interest in non-invasive alternatives that achieve similar therapeutic outcomes. Transcranial temporal interference stimulation (tTIS) is a non-invasive technique delivering two high-frequency currents through scalp electrodes. These currents overlap to produce a low-frequency "beat" capable of reaching deep structures …
