Kevin Bell

Assistant Professor
Bioengineering Department


Dr. Bell is an Assistant Professor in the Department of Bioengineering with a Secondary Appointment in the Clinical and Translational Science Institute. Dr. Bell is a member of the Human Movement and Balance Laboratory and his research interests focus on development and application of portable human movement sensors towards the assessment of joint function throughout the musculoskeletal system. Specifically, clinical and laboratory-based experimentation focuses on assessing the effects of joint injury, repair and rehabilitation to promote more effective clinical treatments and improved clinical outcomes. Novel experimental techniques including virtual reality assisted motion tracking and wireless joint function assessment are utilized to answer clinically relevant research questions. Recent projects have focused on development and validation of a wearable remote rehabilitation system and biomechanical phenotyping of low back pain as a part of the NIH HEAL Initiative's Back Pain Consortium (BACPAC).
