Dr. Duminda Wijeysundera is an Anesthesiologist and Scientist at the Li Ka Shing Knowledge Institute of St. Michael’s Hospital. He is an Associate Professor in both the Department of Anesthesia and the Institute of Health Policy Management and Evaluation at the University of Toronto. He also holds appointments as a Staff Anesthesiologist at Toronto General Hospital and as an Adjunct Scientist at the Institute for Clinical Evaluative Sciences. Dr. Wijeysundera’s research program focuses on developing methods to reduce risks of medical complications following major noncardiac surgery, and evaluating the impact of variation in perioperative processes-of-care on surgical outcomes. His research, which has resulted in more than 100 peer-reviewed publications, has implemented a range of methodologies including prospective cohort studies, randomized controlled trials, and health services research. Dr. Wijeysundera holds a Canadian Institute of Health Research New Investigator Award, while his research program has been supported by the CIHR, Heart and Stroke Foundation of Canada, Ontario Ministry of Research and Innovation, and Ontario Academic Health Sciences Centres Innovation Fund. In addition to his research activities, Dr. Wijeysundera is a member of the American College of Cardiology and American Heart Association Task Force on Practice Guidelines, and is Co-Chair of the Choosing Wisely Canada initiative of the Canadian Anesthesiologists Society.
