I joined the Exercise Science Department at CLU in the Fall of 2007. I teach Exercise Physiology, Advanced Exercise Physiology, Statistics, and Capstone. My research focuses primarily on skeletal health and musculoskeletal aspects of aging. This has included projects investigating bone and muscle changes in response to acute and chronic exercise, aging athletes, and bone differences among various ethnic groups. We've also investigated the critical power concept.
