Current Research Activities: I am interested in gene-nutrient interactions, particularly related to folate and iron metabolism. The projects I am currently focusing on are 1) understanding how alterations in mitochondrial de novo thymidylate biosynthesis plays a role in mitochondrial health and disease, and 2) understanding the impact iron deficiency has on metabolic pathways and physical performance.

Education: B.S. in Nutritional Science, Cornell University
Current Research Activities: My research interests include molecular mechanisms of nutrient metabolism and how these mechanisms change with disease states. My current research project is centered around B-12 and folate metabolism, investigating how these nutrients interact and how they impact mitochondrial function and integrity.
