Dr. Liang-Ching Tsai is an Assistant Professor in the Department of Physical Therapy at Georgia State University dedicated to advancing the research in Physical Therapy with an ultimate goal of better understanding biomechanical injury mechanisms and developing effective interventions to prevent and treat lower extremity injuries. Dr. Tsai completed his training in Physical Therapy from National Taiwan University. He then pursued his M.S. training in Human Movement Science at the University of North Carolina at Chapel Hill and received his Ph.D. degree in Biokinesiology from the University of Southern California. Before joining Georgia State University, Dr. Tsai was a post-doctoral fellow at the Rehabilitation Institute of Chicago and Northwestern University where he focused on robotic rehabilitation. In addition to his passion for research and teaching in Biomechanics, Dr. Tsai enjoys travel and movies and is a fanatic Tar Heels fan.
