Dr. Kumar is a clinician-scientist investigating the biomechanical mechanisms underlying the onset and progression of hip and knee osteoarthritis, and using this knowledge to develop more effective and personalized interventions that may reduce disability and directly impact patient care. At Boston University, Dr. Kumar directs the Movement & Applied Imaging Lab. His lab utilizes biomechanical, imaging, and functional techniques to assess the quality and quantity of movement, tissue health, and disability in people at-risk of or those with hip or knee osteoarthritis. At-risk populations include athletes with femoroacetabular impingement, ACL or meniscus injuries, older adults with obesity, and women. Overarching goal of the research done in the lab is to ensure an active living across the lifespan for people with musculoskeletal conditions.

Dr. Kumar received his entry-level and graduate training in physical therapy in India. He completed his doctorate in biomechanics from the University of Delaware followed by postdoctoral work in advanced imaging of osteoarthritis at the Musculoskeletal Quantitative Imaging Research group at the University of California, San Francisco. Dr. Kumar was an Assistant Professor in the Division of Physical Therapy at the Medical University of South Carolina before joining Boston University. He also holds an appointment in the Clinical Epidemiology Research & Training Unit at BU School of Medicine.
