Dr. Le Gal 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 The Ottawa Hospital, and a Senior Scientist in the Ottawa Hospital Research Institute, Clinical Epidemiology Program.

He was born and trained in France. He received his M.D. degree from the University of Brest in 1997, and completed his residency in Internal Medicine in 2004. He received a Ph.D. degree in Clinical Epidemiology from the University of Brest in 2007. He received fellowship training in Internal Medicine in Brest University Hospital, France, in Angiology in Geneva University Hospital, Switzerland, and completed a clinical and research fellowship in the Thrombosis Program at the University of Ottawa in 2008. Dr. Le Gal went back to France and was appointed a Professor of Internal Medicine at Brest University, before being appointed at the Ottawa Hospital Research Institute in 2012.

Dr. Le Gal’s primary research interest is the diagnosis and management of venous thromboembolism (VTE). He studied the diagnostic value of signs and symptoms for the diagnosis of VTE. Relevant to this application, he developed a clinical decision rule for PE diagnosis in emergency room patients, a clinical decision rule for the diagnosis of DVT in the primary care setting, and participated in the development of a clinical decision rule for recurrent VTE. He also has been involved in many studies that provided external validation for previously derived clinical decision rules. Finally, he developed and validated management strategies for VTE based on the use of these clinical decision rules. Dr. Le Gal has 216 peer-reviewed publications in general internal medicine and specialized journals. 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.
