Skeletal muscle • resistance and endurance exercise • protein and amino acid metabolism • stable isotope tracers • nutrition and muscle health • aging
My research focuses on skeletal muscle protein metabolism and how it is regulated in response to nutrition and physical (in)activity. I am particularly interested in the mechanisms of skeletal muscle loss in humans, which occurs with aging and muscle disuse, and identifying optimal lifestyle interventions focused on exercise and nutritional approaches to protect and restore skeletal muscle mass and strength across the lifespan. My research incorporates stable isotope tracer methods to obtain dynamic measures of muscle protein turnover (i.e., protein synthesis and breakdown) in-vivo in humans. Some of my more recent research has focused on the impact of different sources of dietary protein on myofibrillar and mitochondrial protein synthesis rates following a session of concurrent resistance- and endurance-type exercise. The ultimate aim of my research program is to contribute to improving the overall health, well-being, and physical functioning of our society.
