Caitlyn Pelletier is a Ph.D. candidate in Nutrition, working with Dr. Martha Field. Before coming to Cornell, she earned a B.A. from the University of Pennsylvania in Neuroscience and Nutrition Science. Caitlyn is interested in brain-nutrient interactions and their implications for human health. Now in Dr. Field's lab, Caitlyn is studying the role of folate-mediated one-carbon metabolism on Parkinson's Disease pathology, with a specific focus on mitochondrial dynamics.

Elena Runfeldt is a fourth-year Ph.D. candidate in International Nutrition, working with Dr. John Hoddinott. She earned a B.S. in Nutritional Sciences from Cornell University in 2021. In 2023, she rejoined the Division of Nutritional Sciences after completing a Fulbright fellowship in Barbados, where she designed, implemented, and evaluated a nutrition education program for the Heart and Stroke Foundation’s childhood obesity management initiative, The Yute Gym. Her current research centers on incorporating novel foods into

Chloe is a third-year PhD student in Dr. Martha Field's lab studying folate-mediated one-carbon metabolism (FOCM) and chronic disease. More specifically, she is investigating the roles of folate and vitamin B12 in mitochondrial DNA maintenance and stability, as well as the metabolic consequences of perturbed FOCM. Through her research, she aims to understand how these gene-nutrient interactions shape cellular metabolism and produce biomarkers that reflect health and disease states. In the future, she hopes to

Ashley is a Ph.D. candidate in Molecular Nutrition working with Dr. Shu-Bing Qian, studying mRNA translation regulation, nutrient-sensing pathways, and cellular stress responses. She received her B.Sc. (Hons) in Pharmacology and Biochemistry from the University of Strathclyde through a dual-degree program with China Pharmaceutical University, followed by a master’s degree in Cancer Biology from University College London. Her research interests center on understanding how dysregulated mRNA translation contributes to human disease. She plans to pursue
