Dr. Wijeysundera is a clinician-scientist in anesthesiology and perioperative medicine. He has received, as Principal Applicant, $6 million in peer-reviewed operating grants and salary support awards from CIHR, Heart and Stroke Foundation of Canada, and the Ontario Ministry of Health and Long-Term Care. His other notable recognitions include the 2019 appointment as the inaugural Endowed Chair in Translational Anesthesiology Research at St. Michael’s Hospital and University of Toronto, and a 2014 Early Researcher Award from the Ontario Ministry of Research and Innovation.


Research Synopsis


Dr. Wijeysundera’s research program focuses on developing methods to improve the prediction and prevention of major medical complications following surgery and evaluating the impact of perioperative processes-of-care on surgical outcomes. His research has resulted in more than 230 peer-reviewed publications while implementing a range of methodologies such as prospective cohort studies, randomized controlled trials, and health services research. Dr. Wijeysundera’s 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 editorial board of Circulation, Anesthesiology, and the Canadian Journal of Anesthesia.
