Research | Current

We seek to discover and explain the physiological adaptation of skeletal muscle to exercise or inactivity:

Why does muscle fail to grow or decrease in size and function when it is under-used? How does muscle interpret and respond to exercise stimuli to maintain or increase size and function?

Current studies address these questions in athletic individuals and in older adults, and by using animal models of exercise and aging. The eventual aim of our research is to specify, justify and evaluate interventions to ensure sufficient muscle size and function for movement and metabolic health.
