Research Interests

Dr. Courtman has developed and assessed, both biologically and biomechanically, novel tissue, protein, and cell based biomaterials for use in vascular grafts and heart valves. He has made fundamental contributions to field of vascular pathobiology furthering our understanding of disease progression and tissue material interactions. More recently he has been instrumental in the development of a number of cellular based gene therapies for the treatment of cardio-pulmonary disorders taking them from initial concept, through appropriate animal disease models, and into first in man clinical trials. He is currently directing the manufacturing of these cell products for trials treating patients suffering from pulmonary arterial hypertension, myocardial infarction, and sepsis.

Brief Biography

Dr. Courtman is trained in cellular and molecular pathology and biophysics with extensive expertise in the development of novel therapies for cardiovascular disease. He obtained undergraduate and Master’s degrees in Medical Biophysics from the University of Western Ontario and a PhD in Cellular and Molecular Pathology at the University of Toronto. He completed postdoctoral training in the Vascular Pathobiology program at the University of Washington, Seattle and subsequently took up a position as scientist at St. Michael’s Hospital, Toronto, with an appointment as Assistant Professor in the departments of Surgery, Pathology and Biomedical Engineering at the University of Toronto. In 2008 he moved to the Ottawa Hospital Research Institute to continue his research and take up the directorship the clinical cell manufacturing facility.
