Dr. Laurent Sabbagh obtained his B.Sc. in biochemistry from McGill University. Subsequently, he obtained his M.Sc. degree in microbiology from Laval University under the supervision of Dr. Roger Levesque where he identified novel pathogenesis genes in Pseudomonas aeruginosa. He then obtained his Ph.D. in immunology from McGill University under the supervision of Dr. Rafick-Pierre Sekaly where he studied mechanisms involved in immunological memory of T lymphocytes. Following his doctoral degree Dr. Sabbagh undertook post-doctoral fellowships at the Ontario Cancer Institute and the University of Toronto where he identified novel signaling mechanisms downstream of TNF receptor family members. Dr. Sabbagh opened his laboratory in the fall of 2010 at the research centre of Maisonneuve-Rosemont Hospital where he established a research team working on the role of TNF receptors in immunological memory, inflammation and hematological malignancies. In the fall of 2013, Dr. Sabbagh pursued his research activities on inflammatory bowel disease and polycystic kidney disease at Vertex Pharmaceuticals (Canada). Subsequently between 2017 and 2020, Dr. Sabbagh led research projects aimed on drug discovery of small molecules for the treatment of inflammatory disorders and cancer at Paraza Pharma Inc. in Montreal. Since the spring of 2020, he holds the position of associate director of R&D and head of the biology department at Domain Therapeutics NA Inc.
