Research Interests:

My research focuses on cardiovascular physiology and the influence of aging and lifestyle on the development of cardiovascular disease. There are a number of age- and lifestyle-related changes in the structural and functional properties of arteries that result in impaired vascular function, elevated blood pressure, and contribute to cardiovascular disease risk. I study the effects of intervention, particularly exercise and dietary, on restoration of vascular function and reductions in blood pressure. Additionally, I study physiological and molecular mechanisms responsible for changes in vascular function and blood pressure with aging and following intervention.
