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
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 …

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 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 …

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 …

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 …

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 …

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 …

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 …
