overview

My research focuses on on the genetics of daily physical activity and exercise endurance, as well as the physiological response to high-G exposure and hemorrhage, and the genetics of physical activity. My lab also has a unique interest in the physiological responses of athletes in a variety of non-traditional venues such as auto racing and in musicians.
