Overview

Dr. Powers’ research and teaching interests relate to the biomechanical aspects of human movement. More specifically, his research focuses on how altered kinematics, kinetics, and muscular actions contribute to lower extremity injury. He is particularly interested in the pathomechanics underlying knee and patellofemoral joint dysfunction. He is currently the Co-Director of the Musculoskeletal Biomechanics Research Laboratory and the Director of the Program in Biokinesiology at USC.
