Research Interests

Biomechanics, gene and cell based therapies, clinical trials, polytrauma, fracture healing, implant design, arthroplasty

My research has focused upon the care of patients with musculoskeletal injuries. My basic research interests include the systemic response to trauma, gene therapy, biomechanics, bone substitutes, and the stimulation of fracture healing. My clinical research interests include computer assisted surgery, clinical trials and outcomes studies. I have received international recognition for my research efforts including the Edouard J. Samson Award for a Canadian orthopaedic surgeon with the greatest impact on research in the last five years, the Founder’s Medal for Research (Canadian Orthopaedic Research Society) three times, the Bovill Award for best paper from the Orthopedic Trauma Association twice, the Neer Award from the American Shoulder and Elbow Surgeons, the Best Poster Award from the Orthopaedic Trauma Association twice, the Best Paper Award from the International Society for Fracture Repair, the CORE/ACORE Award from the Canadian Orthopaedic Association, the George Armstrong Peters Award from the University of Toronto, the North American traveling fellowship and the ABC traveling fellowship.

The mission of the Martin Orthopaedic Biomechanics Lab is to measure and improve the biomechanical performance of human and artificial bone, joint replacements and fracture fixation implants, and new biomaterials that can enhance patient quality of life, advance surgical techniques, and reduce health care system costs.

The overall goal of the musculoskeletal research laboratory at St. Michael’s Hospital is dedicated to developing novel biological therapies for non-healing musculoskeletal injuries in bone and soft-tissue, with the ultimate aim being translation to clinical trials in human patients.  Current research is focused on the use of stem cell therapies to improve healing in complex fractures and rotator cuff injuries using animal based models.
