Jeffrey Weitz

Jeffrey I. Weitz, MD is a Professor of Medicine and Biochemistry at McMaster University and Executive Director of the Thrombosis and Atherosclerosis Research Institute.  Board certified in Internal Medicine, Hematology and Medical Oncology, Dr. Weitz now focuses his clinical work in the area of thrombosis. He is a member of the American Federation of Medical Research, the American Society for Clinical Investigation, the Association of American Physicians, and the Canadian Academy of Health Sciences.

Dr. Weitz directs a well-funded research laboratory that focuses on the biochemistry of blood coagulation and fibrinolysis as it applies to venous and arterial thrombosis. A former Vice-President of Research for the Heart and Stroke Foundation, member of the Board of Directors of the Heart and Stroke Foundation of Ontario, Chair of the Scientific Review Committee for the Heart and Stroke Foundation of Canada, member of the Executive Council on Thrombosis of the American Heart Foundation, and Chair of the Council on Vascular Biology for the American Society of Hematology,

Dr. Weitz has published over 375 peer-reviewed papers and 50 textbook chapters on thrombosis or fibrinolysis. By focusing on the basic mechanisms by which anticoagulants (blood thinners) and thrombolytic agents (clot digesting drugs) work, Dr. Weitz has opened new avenues of investigation. His demonstration that thrombin bound to fibrin is resistant to inactivation by available anticoagulants stimulated the development of new drugs, some of which are already being used in clinical practice.
