Duncan Stewart – President and Scientific Director

Dr. Duncan StewartDuncan is a pioneering Canadian cardiovascular researcher who is recognized for his many important discoveries in blood vessel biology, as well as his dedication to translating these discoveries into benefits for patients and society.
After beginning his career in academic cardiology at McGill University in Montreal, he moved to Toronto as Head of Cardiology at St. Michael’s Hospital and later became Director of the Division of Cardiology and Executive Director of the McLaughlin Centre for Molecular Medicine at the University of Toronto. He was recruited to lead the Ottawa Hospital Research Institute in 2007.Duncan has made a number of seminal discoveries elucidating the importance of endothelial factors in health and disease, notably the role of the nitric oxide system in angiogenesis and of endothelin-1 in pulmonary hypertension.
Duncan is also a leader in developing cell and gene based therapies for cardiovascular disease. He led the first Canadian clinical trial to test an angiogenic gene therapy – using VEGF to try to stimulate heart repair in people who had suffered heart attacks. He also led the world’s first clinical trial of a gene-enhanced cell therapy for pulmonary hypertension, using endothelial progenitor cells engineered to over-express the endothelial nitric oxide synthase. He also leads the world’s first clinical trial of a similar therapy for post heart-attack repair, and he has played a key role in initiating the world’s first trial of mesenchymal stem cells for the treatment of septic shock.
Duncan has published more than 200 peer-reviewed manuscripts and has received a number of distinctions and prizes, including the Dexter Man Chair of Cardiology and Research Achievement Award of the University of Toronto, and the Research Achievement Award of the Canadian Cardiovascular Society.
Throughout his career, Dr. Stewart has demonstrated leadership in bringing diverse groups of clinicians and scientists together to put Canada on the world stage for translational cardiovascular and regenerative medicine research.
