2025 Sandia Graduate Fellows

Welcome to the outstanding graduate students selected for the 2025 URA Sandia Graduate Summer Fellowship! Learn more about our 2025 Fellows below.

Tyler Bernard, University of California Berkeley

As a first-year PhD student in Environmental Science, Policy, and Management at UC Berkeley, I develop computational approaches to understand how microbial communities influence ecosystem carbon cycling. My research combines ecological modeling with machine learning to bridge molecular and ecosystem scales, aiming to improve predictions of carbon dynamics in natural systems. At Sandia, I will apply these methods to algal biofuel systems, leveraging their controlled environment to validate computational frameworks before scaling to more complex ecological applications. Beyond research, I write about the intersection of environmental science and philosophy on my blog Only the Wild Ones, and I can usually be found running, swimming, biking, or skiing, depending on the time of year.

Andrew DeRuiter, University of Minnesota Twin-Cities

As a fourth-year PhD candidate in Materials Science and Engineering at the University of Minnesota Twin-Cities, I study how to improve the properties of the rare-earth free permanent magnet candidate α′′-Fe16N2. My project focuses on the enhancement of the coercivity of iron nitride, using thin films synthesized with facing-target-sputtering as the testing bed for our efforts. At Sandia, I will be broadening my knowledge of thin film deposition, studying the combinatorial synthesis of spin transition oxides via pulsed laser deposition. Outside of work, I am an avid foodie, an active bookworm, and enjoy playing video games.

Dylan Joralmon, Arizona State University

I am a 2nd year mechanical engineering PhD student from Arizona State University currently working with Prof. Xiangjia (Cindy) Li. During my time at ASU, I have become interested in studying a vast range of additive manufacturing technologies to fabricate functional metals, alloys, and multi-metal components with enhanced physical properties at faster printing speeds. At Sandia, I am excited to be working on DLP-based 3D printing technologies to generate non-linear mechanical responses and look forward to contributing valuable insights into this project. Outside of research, I’m an avid reader and my hobbies include astronomy, camping, building computers, and playing hockey.

Molly McDonough, Pennsylvania State University

I’m a third year Materials Science and Engineering Ph.D. Student at Penn State working with Dr. Stephanie Law. Prior to graduate school, I received by BS in Physics from Suffolk University. My research is focused on synthesis and development of thin-film materials for applications in infrared technology. At Sandia, I will be working on developing a photoreflectance setup for the characterization of semiconductor materials and devices to gain insight into the material and device performance. Outside of the lab, I enjoy reading, weightlifting, and needlework. 

Sam Kaufman-Martin, University of California Santa Barbara

 

As a 7th-year PhD candidate in Mechanical Engineering at UC Santa Barbara, I study the aerodynamic wakes of annular actuator discs. Informed by data from my wind tunnel experiments with porous rings, I develop reduced-order theoretical wake models, which can be used to efficiently model the wakes of airborne wind energy kites. At Sandia, I will be joining the FLOWMAS project, where I will run high-fidelity simulations of floating offshore wind turbines and use them to develop lower-fidelity, physics-based wake models. In my free time, I enjoy bicycling, playing board games, and reading science-fiction and fantasy novels. 

Tyler Kirby, Arizona State University

I am currently a first year Electrical Engineering PhD student at Arizona State University where I also received a M.S. in Electrical Engineering. I am a Bay Area, California native and I resided there until I graduated from Santa Clara University with a B.S. in Engineering Physics. My research interests include the physics, fabrication, and modeling/simulation of microelectronic devices, as well as how these devices are affected by radiation. Outside of my research I like to play and watch sports, ride my bike, and barbeque. 

Eric J. Pabón Cancel, Purdue University

 

 

Hello there! I am Eric, a 2nd year PhD student in Mathematics at Purdue University. My current research interests are in Dynamical Systems and Machine Learning methods. My latest research was in Generative Artificial Intelligence and Mathematical Algorithms, where I applied clustering methods and Principal Component Analysis to determine the optimal autoencoder for sequences of unlabeled data. My work at Sandia is on Machine Learning applications for Data Driven Closure Models. I earned my Bachelor of Science degree in Mathematics from the University of Puerto Rico, Mayagüez Campus. After completing my graduate studies, I aspire to become a mathematical research scientist, and outside of academics I like to make origami figures and play percussion instruments. 

 

Electra Scarpignato, Boston University

I am a first-year MS student studying Biomedical Engineering at Boston University. My research interests are in the intersection of biological and computational research. I have previously researched in a cardiovascular tissue engineering laboratory and separately on a hydrology project utilizing machine learning. My current research is in a Systems Immunology lab utilizing computational methods to identify disease trends and make predictions from high-dimensional immunology data. At Sandia, I am excited to develop advanced cell-based systems for rapid testing of potential therapeutics. Outside of research, I enjoy hiking, cooking, and exploring local coffee shops.
