Dr. Kenneth Holt is a professor in the Movement and Rehabilitation Sciences program at Boston University. He also directs the Barreca Laboratory for Motion Analysis where he studies locomotion and other gross motor development using mechanical and dynamic models. He is currently a visiting professor at the Wyss Institute For Biologically Inspired Engineering at Harvard University. At this institute he is involved in the development of biologically inspired exoskeletons to promote body support in functional situations. His main research interests include the biomechanical analysis of gait and non-linear models (with a particular application to gait disorders), including the associations with cerebral palsy, Down’s Syndrome, Parkinson’s disease, and the risks of falling in old age. His particular interest in developing rehabilitation methods is based on Dynamical Systems theory. The U.S. Department of Education, the Physical Therapy Foundation, the United Cerebral Palsy Foundation, the U.S. Army, and the National Institute on Aging have all provided support for Dr. Holt’s research. He is also affiliated with the U.S. Army Research Unit (USARIEM) in Natick, Massachusetts, where he studies the effects of load carrying on movement coordination patterns. He is an adjunct associate professor at St. Augustine University in Florida and his professional affiliations include the International Society for Ecological Psychology and the American Physical Therapy Association. His work has been presented extensively in forums in Psychology, Motor Control, Biomechanics, and Physical Therapy.
