Peter Barrance, PhD, is a senior research scientist in the Center for Mobility and Rehabilitation Engineering Research and director of the Musculoskeletal Biomotion Research Laboratory at Kessler Foundation. He is also a research associate professor in the Department of Physical Medicine and Rehabilitation at Rutgers New Jersey Medical School. Dr. Barrance received a Bachelor of Science degree in engineering science and a Master's degree in engineering mechanics at Iowa State University. He received research experience as a biomedical engineer in the Orthopaedic Biomechanics Laboratory at Johns Hopkins University. He pursued his Doctoral degree in mechanical engineering at the University of Delaware, participating in interdisciplinary rengsearch with advisership by both engineering and physical therapy faculty. In his dissertation work he developed and deployed a method to analyze knee joint motion in individuals with ligamentous injury using dynamic MRI. Following a two-year postdoctoral fellowship at the University of Delaware, he joined Kessler Foundation in 2006 where he has continued to pursue research in disability with musculoskeletal origins, including weight-bearing imaging of the knee joint in individuals with knee joint osteoarthritis.
