Dr. Marc Rodger, Chair of the McGill Department of Medicine, is a world leading researcher in venous thrombosis. His work that confirmed a link between common blood clotting tendencies and pregnancy complications, showed that injectable blood thinners do not prevent these complications (a previously common practice), defined the long-term risk of developing recurrent venous thrombosis and identified high risk sub-groups that merit continuing blood thinners lifelong. Dr. Rodger co-founded the Canadian Venous Thromboembolism Research network and founded the INVENT network (www.invent-vte.com), an international VTE research network that includes over 450 members in over 150 sites collaborating on venous thrombosis clinical trials.
