RESEARCH INTERESTS

My research areas are injury biomechanics and sports biomechanics. I utilize motion, force, electromyography measurements, and musculoskeletal modeling to understand injury mechanisms and develop injury prevention and performance training strategies.  My current research is focused on jump-landing mechanics and anterior cruciate ligament injuries, baseline and post-injury strength and balance assessments for collegiate athletes, and biomechanics of strength and conditioning exercises.
