PhD, MSc

Associate Scientist, Li Ka Shing Knowledge Institute


Dr. General Leung is the Magnetic Resonance Physicist at the MRI Research Centre at St. Michael’s Hospital. He is also an Assistant Professor at the University of Toronto in the Department of Medical imaging. He co-chairs the SMH MR Research committee and oversees the day to day operation of the SMH MRI Research centre. His primary research interest is in development of MRI techniques applied to the vascular system. In particular, he has been studying the magnetic properties of blood and the effects of methemoglobin on plaque vulnerability.
