Neuroscience Program Student Scholarship

Tessa Medeiros ’26, Biology & Psychology major

Faculty mentor: Dr. Andra Geana, Psychology and Neuroscience

Reinforcement learning (RL) mathematically describes how agents learn to maximize the reward of their environment by understanding and comparing their choice options. This project investigates how anxiety and compulsivity impact the selection of these options and to what extent a text-based, narrative (rather than a game-like environment) changes RL processes in humans.

Gerrymandering And How To Find It: A Mathematical Approach, Nicholas Small

Mathematics & Computer Science Student Scholarship

Nicholas Small ’25, Mathematics and Computer Science major

Faculty mentor: Dr. Liam Donohoe, Mathematics and Computer Science

Gerrymandering is a phenomenon that has plagued American politics for over 200 years. This process, which involves redrawing congressional and legislative district boundaries to favor one group over another, has become a fact of life in the past few decades. This project explores the history of gerrymandering and some of the algorithms proposed to combat it. The two main strategies of Gerrymandering are packing—or limiting the other group’s influence by making them the extreme majority in a few districts—and cracking—or splitting up a …

Examining Repetitive Negative Thought Among Individuals With Eating Disorders, Laney Manware

Psychology Student Scholarship

Laney Manware ’25, Psychology major

Faculty mentor: Dr. Emily Gentes, Psychology

Repetitive negative thought (RNT), encompassing both rumination and worry, has been increasingly recognized as a significant factor in eating disorders. While rumination has been both concurrently and prospectively linked to eating disorder symptoms, the relationship between worry and eating disorders remains less explored (Smith et al., 2018). This study examines worry in individuals with anorexia, binge eating disorder, and bulimia using data from the National Comorbidity Survey Replication. Results show that those with binge eating disorder or bulimia report more worry than those without eating disorders, suggesting that worry …

Sample Preparation And Acquisition Strategies To Improve Accessibility And Proteome Depth In Single-Cell And Low-Input Proteomics, Sara Madisyn Johnston

Theses and Dissertations

Proteins are responsible for important cellular functions and processes including regulation, structural integrity, signaling, transport, and immune functions. Proteomics directly identifies these proteins and enables deeper characterization of the dynamic cellular environment beyond the capabilities of genomics and transcriptomics. Single-cell proteomics further enhances this approach by capturing cellular heterogeneity, which bulk proteomics obscures due to averaging protein expression across large cell populations. Despite significant advances in single-cell proteomics, continued innovation is necessary to increase workflow accessibility and throughput, minimize peptide losses, and achieve comprehensive coverage of the proteome. This dissertation addresses these challenges by developing improved sample preparation methods, two-dimensional …

Eleanor Fortescue-Brickdale And The Best, The Worst, And The Betwixt: The Intertwined Women Of Arthurian Literature And Victorian Society, Hannah Johansson

Theses and Dissertations

The late Victorian and early Edwardian artist Eleanor Fortescue-Brickdale’s illustrations and paintings have been largely marginalized in the larger world of Arthurian art and criticism. This thesis argues that her work, focused on the illustration Enid, Guinevere, and Vivien, is impactful in its exploration between Arthurian characters and Victorian women. Critiquing with a feminist ideology, Brickdale attempts to break down Victorian stereotypes on women by visually breaking down the socially congruent labels placed onto the women of Camelot. In doing so, she both critiques Victorian society and artistically argues for a much needed social reconstruction.

Biology Student Scholarship

Owen Finnegan ’25, Environmental Biology major

Faculty mentor: Dr. Jeffrey Markert, Biology

Here we test whether eDNA concentrations consistently reflect the abundance of fish in a given area. We compare physical catches to the levels of eDNA in the water using quantitative PCR (qPCR) at three sites in Rhode Island. A native and plentiful species like Atlantic Silversides is the perfect organism to for calibrating our methods as recorded catches of Atlantic Silversides from our collections range from 0-1500+ individuals.

The Effect Of Salinity On Mangrove Growth In The Florida Everglades, Olivia Macaluso

Biology Student Scholarship

Mangrove forests are highly productive ecosystems that provide benefits to humans, such as storm protection, in the intertidal regions of tropic and subtropic climates. Mangroves grow primarily in shallow brackish water where fresh and salty water sources meet, but frequent hurricanes mean that once stable brackish environments are vulnerable to fluctuations in salinity levels. A previous study on the effect of salinity on mangroves found a negative relationship between salinity increase and root biomass growth. However, little research has gone into the effects of salinity changes on mangrove growth and productivity. Here, I used data from the Wetland and Aquatic …

Environmental Racism In Ri: The Presence Of Toxic Waste Sites In Low Income And Minority Communities (19), Julienne Walsh

Biology Student Scholarship

Environmental racism refers to the disproportionate impact of environmental hazards on communities of color and low-income populations. Across the U.S., studies have shown that polluting facilities are more likely to be in or around communities with higher percentages of non-white residents or lower socioeconomic status. Scholarship regarding these patterns in small states like Rhode Island is relatively limited. By analyzing how these sites are spatially distributed in relation to racial and economic demographics, this research aims to contribute to a deeper understanding of local environmental inequities. I hypothesize that if you live in a low-income or more diverse town, national …

5-Ht Receptors: Pharmacology And Functional Selectivity, Benjamin R. Cummins, Gerald B. Billac, David E. Nichols, Charles D. Nichols

School of Medicine Faculty Publications

Serotonin 5-HT receptors were one of the first serotonin receptors to be pharmacologically characterized. In mammals, they are expressed throughout the body in nearly every cell and tissue type, with the highest density in cortical layer V of the brain. They are involved in several aspects of normal physiological processes and behaviors and have been implicated in the etiology of neuropsychiatric diseases such as schizophrenia. Atypical antipsychotics have targeted blockade of 5-HT receptors as part of their therapeutic mechanism. More recently, 5-HT receptors have come to prominence for their role as the primary target for psychedelic drugs, which activate this …

Porous Hierarchically Ordered Hydrogels Demonstrating Structurally Dependent Mechanical Properties, Elisabeth C. Lloyd, Sujata Dhakal, Shahrouz Amini, Rami Alhasan, Peter Fratzl, Douglas R. Tree, Svetlana Morozova, Robert J. Hickey

Faculty Publications

While hierarchical ordering is a distinctive feature of natural tissues and is directly responsible for their diverse and unique properties, efforts to synthesize biomaterials have primarily focused on using molecular-based approaches with little emphasis on multiscale structure. Here, we report a bottom-up self-assembly process to produce highly porous hydrogel fibers that resemble extracellular matrices both structurally and mechanically. Physically crosslinked nanostructured micelles form the walls of micrometer-sized water-rich pores with preferred orientation along the fiber direction. Low elastic moduli (< 1 kPa), high elasticity (extending by more than 12 times the initial length), non-linear elasticity (e.g., hyperelasticity), and completely reversible extension are derived from unevenly distributed strain between the micrometer-sized pores and the polymer chains, which is reminiscent of cellular solids. Control of the material microstructure and orientation over many orders of magnitude (e.g., nm–μm), while holding the nanostructure constant, reveals how the multiscale structure directly impacts mechanical properties.

Efficiency’S Role In Irrigation And Nitrogen Use, Matt Stockton, Shannon Sand

Cornhusker Economics

Summary

The WNIPI is a purely physical measure of I and N efficiency and was developed to determine efficiency winners in several TAPS contests. DRIN is a powerful tool in measuring the effectiveness of the dollars spent on I and N. It is a ratio of dollars returned as revenue in terms of dollars spent. The third measure, NRIN, is an overall measure of economic gain. It is the difference in money spent on I and N versus the revenue taken in and measures the volume of net returns. Both DRIN and the NRIN measure dollar effectiveness dependent on the …

Microwave Frequency Probes Of Graphene, Xinyi Du

Arts & Sciences Graduate Student Theses and Dissertations

We investigate high-frequency microwave spectroscopy as a probe of the electronic structure of graphene, focusing on compressibility, magnetic response, and the potential for detection applications. Graphene is a single layer of carbon atoms arranged in a hexagonal lattice, exhibiting unique electronic properties due to its band structure and reduced dimensionality. While traditional compressibility measurements rely on low-frequency capacitance techniques, this thesis explores a high-frequency approach using superconducting resonators to probe the compressibility of graphene in the GHz regime. Originally conceived as a means to examine the diamagnetic response, the method faces fundamental limitations due to resistive losses, revealing key challenges …

What Happens In The Shadows: Racial Hierarchy And The Policing Of People Of Color, Nanditha Vinod

English and Creative Writing Presentations

In this presentation, I examine the relationship between methods used in graphic memoirs by illustrators to depict and critique political and social inequalities. I specifically analyze the graphic memoir Guantanamo Kid by Alexandre Franc and Jérôme Tubiana, which depicts the brutal experience of Mohammed El-Gharani, who was falsely imprisoned in Guantanamo Bay as a child. I argue that the illustrators manipulate the composition of lights and shadows to emphasize racial hierarchy and the inherent power imbalance between people of color and white bodies that severely restrict agency. The usage of lights and shadows, often overlooked in visual arts, heightens the …
