Honors Projects

This honors project examines how emerging aviation technologies can support or automate components of Pilot Weather Reports (PIREPs) to improve reporting accuracy, reduce pilot workload, and increase participation within the general aviation (GA) community. PIREPs provide essential real-time weather observations—such as turbulence, icing, and visibility—that supplement automated systems and enhance situational awareness for pilots, air traffic control, and meteorologists. However, reports are vastly underutilized due to workload constraints, inconsistent training, voice-only submission methods, and technological disparities across the GA fleet.

Through a structured analysis of federal aviation documentation, sensor capabilities, human factors research, and recent advancements in automation, this study …

Housing Burden And Insurance Expenditures, Melanie M. Lytell

Honors Capstones

Housing costs shape the way families spend on protection and security. This study looks at how the share of income devoted to housing, the housing burden, influences household spending on four types of insurance: vehicle, life, personal, and health. Using data from nearly 92,000 households and regression models that account for state differences, I find that even small increases in housing burden shift insurance choices in meaningful ways. A one‑percentage‑point rise in housing burden is linked to a 2.1% increase in vehicle insurance spending and a 0.5% increase in life insurance, but a 0.7% decrease in personal insurance and a …

Iphone-Based Image Refocusing, Katie Jeong, Daniel Niu

Electrical and Systems Engineering Capstone Design Projects

In this project, we show that we can change the focus of a picture after we take it by using real optical physics instead of fake software blur. Modern phones try to create “portrait mode” effects, but those results are often not physically correct. Our approach uses multiple photos taken from slightly different positions to figure out the directions that light rays came from in the scene.

To collect the photos, we move an iPhone sideways on a slider in small, precise steps. Since we know exactly how far the phone moved for each picture, we can track how objects …

Ethical Review Of Discipline-Based Education Research: Ensuring Fair Treatment For All, E. Elias Johnson

Undergraduate Honors Theses

As universities grapple with funding cuts and heightened social and political pressure, the emerging field of Discipline-Based Education Research (DBER) aims to improve student learning outcomes through experimental instruction. While using instruction as an experiment, with hypotheses and experimental tests, DBER research may affect student learning and experience in unintended ways for students involved in these classes. To address this concern, I impose ethical frameworks, namely contractualism, to better understand how the values of each stakeholder, students enrolled in experimental courses and researchers using these courses to test hypotheses, interact. I also identify potential misalignments. Following a contractual ethical framework, …

Measuring Levels Of Ultrashort-Chain Per- And Polyfluoroalkyl Substances In Blood Collection Tubes, Alina M. Dziembowski

Discovery Undergraduate Interdisciplinary Research Internship

Per- and polyfluoroalkyl substances (PFAS) are highly persistent synthetic chemicals that are now ubiquitous in the environment. Due to PFAS stability leading to its environmental persistence, there is concern regarding potential long-term health effects as PFAS accumulation occurs in humans from dietary and inhalation exposure routes. Chronic exposure may lead to adverse effects such as fertility issues or liver damage. Although a wide range of PFAS have been found in human samples, specifically human serum, there remains data gaps for what PFAS are present in human blood. Recent innovation in detection technology has led to the ability to more accurately …

Daniel Cárdenas-Vásquez, Hatte Hamilton, Megan Hicks, Daniel Mattar, Kyle Choy, Marco Bisoffi, L. Andrew Lyon

Engineering Faculty Articles and Research

The fabrication of a new class of biomimetic biomaterials is reported using nanostructured microgel pastes formed from “overpacked” assemblies of ultrasoft poly(N-isopropyl acrylamide-co-acrylic acid) microgels and their composites with collagen. Despite the solid-like nature of microgel pastes, collagen fibrillogenesis is robust and rapid, with a 3D collagen network forming throughout the paste volume. Structural organization within the composite is interrogated via a suite of microscopy methods, while rheological characterization provides insight into the static and dynamic mechanical properties of the materials. Long-range fibrillogenesis is enabled by local crowding, dynamics, and spatial reconfigurability of pastes at the …

Ract: Ranking-Aware Chain-Of-Thought Optimization For Llms, Haowei Liu, Xuyang Wu, Guohao Sun, Hsin-Tai Wu, Zhiqiang Tao, Yi Fang

Computer Science and Engineering

In information retrieval, large language models (LLMs) have demonstrated remarkable potential in text reranking tasks by leveraging their sophisticated natural language understanding and advanced reasoning capabilities. However, conventional supervised fine-tuning approaches for specializing LLMs in ranking tasks often lead to significant degradation of the models' general-purpose abilities. To address this fundamental challenge, this paper presents a novel methodology that strategically combines Chain-of-Thought (CoT) prompting techniques with an innovative two-stage training pipeline consisting of Supervised Fine-Tuning followed by Ranking Preference Optimization (SFT-RPO). The Chain-of-Thought prompting component encourages models to explicitly articulate their reasoning process during ranking decisions, creating a transparent pathway …

Here, we characterized a polyethylene glycol surface modification of composite silicon–PDMS membranes to evaluate their effects on microfluidic oxygenator properties. X-ray photoelectron spectroscopy (XPS) and water contact angle goniometry confirmed successful PEG attachment, evidenced by the presence of characteristic C-O bonds and increased hydrophilicity, which was stable for 2 weeks. …

Adaptive Image Acquisition Algorithms For Resource-Constrained Single-Photon Cameras, Yeganeh Jalalpour, Wu-Chi Feng

Computer Science Faculty Publications and Presentations

Emerging single-photon camera (SPC) technologies have unique challenges in data acquisition and processing. Unlike conventional sensors that produce a single 8- to 16-bit brightness value per pixel, SPCs record photon arrivals with many more samples per pixel, using high floating-point precision for each photon collected. This means that they must handle potentially millions of timestamps, especially at higher spatial resolutions and in the presence of ambient light, creating bottlenecks within the pixel circuitry. To address these challenges associated with SPCs, this paper proposes adaptive algorithms designed to efficiently distribute hardware resources among groups of pixels. By selectively subsampling the data …

Strategies For Prolonging Ventricular Action Potential Duration Without Increasing Transmural Dispersion Of Repolarization, Candido Cabo

Publications and Research

Dispersion of repolarization results from a non-homogeneous recovery of excitability in cardiac tissue, and it is an important factor in arrhythmogenesis because it could lead to the initiation and maintenance of a variety of arrhythmias. Antiarrhythmic agents that prolong action potential duration (APD) by selectively blocking specific ion channels (like IKr) often increase dispersion of repolarization, which could result in a pro-arrhythmic risk. In this report, using computer models of the action potential of human epicardial, mid-myocardial, and endocardial myocytes, we have identified strategies to prolong APD without increasing transmural dispersion of repolarization. The first strategy, which involves blocking several …
