Research Interests
Dr. Jan is Director and Associate Professor of Rehabilitation Engineering Research Lab in the Disability Resources and Educational Services. He is committed to developing rehabilitation technologies for the prevention and management of secondary conditions in people with impaired mobility. Dr. Jan is recognized for his research on soft tissue biomechanics and its role in the development of musculoskeletal injury, including pressure injury. Dr. Jan has extensively published his research work to improve the understanding of the effect of various pathophysiological conditions (spinal cord injury, aging, diabetes, physical inactivity) on musculoskeletal injury. His research has been supported by the NIH, NIDRR, PVA Foundation and Reeve Foundation. Dr. Jan serves as an associate editor on prestigious journals, including the Journal of NeuroEngineering and Rehabilitation, Frontiers in Bioengineering and Biotechnology, Frontiers in Physiology, and PLOS ONE, and is an editorial board member of the Assistive Technology and Journal of Tissue Viability.
