Molecular and Cellular Science
The overall goal of my research program is to elucidate the mechanisms by which diet and exercise influence vascular health and the prevention of cardio-metabolic disease. Specifically, I focus on signaling pathways in endothelial cells, which are the monolayer of cells that line the lumen of the vasculature. This highly specialized cell layer is responsible for rapidly reacting to changes in organ demand, such as nutrient deprivation or low oxygen. While diet and exercise are known to be important for the prevention of cardio-metabolic diseases, the molecular mechanisms underpinning their benefits are only beginning to come to light. My current research has identified a critical role for reactive oxygen species (ROS) signaling in adaptive responses to diet and exercise, and understanding the molecular pathways that respond to these will pave the way for targeted therapies in cardio-metabolic disease.
