Dr. Grégoire Le Gal, M.D., Ph.D., is a Professor in the Division of Hematology of the Department of Medicine at the University of Ottawa, a physician in the Thrombosis Program, Division of Hematology at Ottawa Hospital, and a Senior Scientist in the Ottawa Hospital Research Institute, Clinical Epidemiology Program since July 2012. He was born and trained in France.
His primary research interest is the diagnosis and management of venous thromboembolism (VTE), including the clinical diagnosis of VTE, and the derivation and validation of clinical decision rules for VTE. He has 233 peer-reviewed publications in general internal medicine and specialized journals and has had multiple international speaking invitations. He is a member of the international advisory board of the Journal of Thrombosis and Haemostasis, and a reviewer for main general internal medicine and thrombosis Journals. He has been the principal investigator of several multicenter multinational projects on the diagnosis and management of VTE.
