Research Interests

Multiple sclerosis (MS), MRI, spinal cord, clinical trials

Research Activities

I am leading development of the MRI in the MS research program at St. Michael’s Hospital. I am conducting a number of clinical research projects evaluating the use of advanced MRI techniques in the spinal cord in patients with various sub-types of MS.
