Interests & Expertise

Dr. O'Connor's primary research focus is on the biomechanics of musculoskeletal injury. Current research has focused on the mechanisms knee injuries that occur during sports, and particularly the effects of fatigue on increased injury risk. The effects of fatigue may be central to understanding overuse running injuries such as anterior knee pain and traumatic injuries such as anterior cruciate ligament (ACL) tears. Neuromuscular fatigue may also be a factor contributing to musculoskeletal disease progression such as with osteoarthritis. Dr. O’Connor has also been actively involved in developing a new motion capture technology to track motion in three-dimensions using a single camera. This will allow for a portable system for testing in a clinical setting that avoids the need to bring populations to specially-equipped labs.
