Adam S. Lepley Ph.D., ATC


Program Director, Professional Athletic Training Program

Assistant Professor in Residence, Department of Kinesiology


Academic Degrees:

Ph.D. University of Toledo, 2014

M.A. University of Minnesota, 2010

B.S. Grand Valley State University, 2008


Areas of Expertise:

Neuromuscular function, Cortical changes following musculoskeletal injury, Neural excitability, Knee injuries, Anterior cruciate ligament reconstruction


Dr. Adam Lepley’s research interests are focused on maximizing clinical outcomes following musculoskeletal injury, specifically involving the knee. In particular, Dr. Lepley examines the neural contributions to muscle dysfunction and their involvement in lower extremity biomechanical and self-reported disability. The overall goal of this research is to identify the origins of persistent neuromuscular dysfunction for the purpose of developing targeting rehabilitation strategies that are capable of maintaining long-term joint health following acute injury.
