Christopher M. Powers, PT, PhD, FAPTA is Professor in the Division of Biokinesiology and Physical Therapy and Co-Director of the Musculoskeletal Biomechanics Laboratory at the University of Southern California. 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. Dr. Powers is an active researcher, and has published over 150 peer-reviewed articles. He frequently lectures both nationally and internationally on topics related to lower limb biomechanics and the pathomechanics of orthopaedic disorders.
