Glenn Fleisig, PhD, earned his engineering degrees from MIT, Washington University, and UAB. Dr. Fleisig is the Director of Biomechanics at the American Sports Medicine Institute, where he has been since ASMI’s inception in 1987. Much of ASMI’s research under Dr. Fleisig has focused on baseball pitching biomechanics, identifying mechanics for minimizing elbow and shoulder loads while maximizing ball velocity and accuracy. Dr. Fleisig and his team have analyzed thousands of athletes, from youth to professional levels, providing individualized recommendations for safety and performance.

Dr. Fleisig has published more than 200 scientific articles, book chapters, and books in collaboration with colleagues at ASMI and other institutions. He has delivered 400 presentations throughout the world and has been interviewed for thousands of stories by the media. Dr. Fleisig has supervised more than 250 student researchers (biomechanical and medical) at ASMI.

Dr. Fleisig is a fellow of ISBS and the American Society of Biomechanics and also serves as an adjunct professor in biomedical engineering at UAB. In addition, Dr. Fleisig works on policy and guidelines as a member of the USA Baseball Medical & Safety Advisory Committee, injury research advisor for Major League Baseball, and safety consultant for Little League Baseball. Dr. Fleisig was also the founding president of the American Baseball Biomechanics Society.
