Professor

Professor Yijian Yang is a member of the International Society for Posture and Gait Research (ISPGR) and the Gerontological Society of America (GSA). He directs the Sports Biomechanics and Injury Prevention Laboratory, which studies musculoskeletal biomechanics related to human health and mobility. A key focus of the laboratory is the prevention of fall-related injury (e.g., traumatic brain injury, hip fracture) in older adults. Particularly, the team seeks to understand biomechanical and physiological risk factors for injury and mobility impairment in older adults, and to develop and evaluate novel interventions for injury prevention. Their goal is to conduct high quality and evidence-based research that will lead to significant impact on older people’s health and quality of life.
