Experience & Interests
Dr. Ajit Chaudhari has been a member of the faculty at OSU since 2006. His research focuses on the basic question: Can we better understand how musculoskeletal injuries and conditions happen by studying the human body as a mechanical system? In particular, Dr. Chaudhari is  interested in the role of core stability in the prevention and treatment of injuries across the entire body in aging, chemotherapy, orthopedics, and hernia, and in understanding and improving balance, gait, and mobility across the lifespan. He has worked with athletes from several OSU and professional sports teams, as well as the OSU Dance department and BalletMet. His research has been sponsored by organizations such as the National Football League, National Institutes of Health, National Highway & Transportation Safety Administration, National Science Foundation and industrial sponsors.
Dr. Chaudhari has authored numerous articles and book chapters on the biomechanics of gait and athletic injury and is a reviewer for several sports medicine, kinesiology, orthopaedics and biomedical engineering journals. He is currently a member of the American Society of Mechanical Engineers, Orthopaedic Research Society, American Society of Biomechanics and a Fellow of the American College of Sports Medicine.

Research Interests
Mike’s dissertation investigated how how energy is transferred from the ground to the hand during baseball pitching, and the effects of perceived workload and pitch counts on pain and overuse injuries in high school aged baseball pitchers. This research aims to lead to a better understanding of how biomechanics can help pitchers perform at their highest level while minimizing the potential for damage to their arm, and hopes to provide evidence based recommendations for pitch counts in high school baseball.
