Chair and Associate Professor of Exercise & Sport Studies

Sarah Witkowski


Scott Gym 405


Sarah Witkowski is an exercise physiologist whose research focuses on cardiovascular physiology. The overall goal of her research is to understand the cells and signals that promote blood vessel health, repair and regeneration. Recently, she has investigated female-specific conditions, such as menopause, that increase risk for cardiovascular disease and the role that physical activity and fitness play to alter the female risk trajectory.

Witkowski has a strong background in sports and coaching as she has coached all levels, from youth to division I intercollegiate sports. She has coached at numerous camps and clinics nationally and internationally, including instructional clinics for coaches. Prior to her doctoral training, Witkowski held a position at the Institute for Exercise and Environmental Medicine in Dallas that included performance testing of young and older athletes.
