Dr. Jeffery Rankin is the Associate Director of the Pathokinesiology Laboratory and Co-director of the Rehabilitation Engineering Department at Rancho Los Amigos National Rehabilitation Center. He received his Ph.D in Mechanical Engineering from the University of Texas at Austin, with a research focus in using state-of-the-art musculoskeletal modeling and computer simulation methods to understand movement. Dr. Rankin uses engineering principles to better understand movement in order to develop rehabilitation devices and approaches that improve patient outcomes. His research interests in movement are far-ranging: in addition to Dr. Rankin’s primary clinical interests in manual wheelchair propulsion and human gait, he has also conducted research to better understand cycling biomechanics and non-human movements like ostrich running and kangaroo rat jumping. Dr. Rankin’s expertise in modeling and simulation work is recognized internationally and he regularly presents his research findings at national and international conferences.
