Warren Lee


Scientist, Keenan Research Centre for Biomedical Science


Dr. Lee received his MD from the Faculty of Medicine at the University of Toronto and was awarded the Cody Gold Medal. He completed residencies in Internal Medicine, Respirology, and Critical Care Medicine in Toronto. He then undertook research training in the Programme in Cell Biology at the Hospital for Sick Children in the laboratory of Dr. Sergio Grinstein, completing a doctorate in 2006. This was followed by postdoctoral training in Microbiology and Immunology at Weill Medical College of Cornell University (New York, NY) in the laboratory of Dr. Carl F. Nathan. Dr. Lee’s research focuses on the mechanisms of endothelial permeability, a process that determines how fluid, cells and molecules are retained inside blood vessels.
