Kenneth Croitoru

Dr. Kenneth Croitoru is a Gastroenterologist specializing in IBD and a Clinician-Scientist in the Department of Medicine, Luenefeld Tannenbaum Research Institute at Mount Sinai Hospital (Toronto), and a Professor of Medicine and Immunology at the University of Toronto. To date, he has over 100 scientific publications with more than 4500 citations.

After completing his medical training in internal medicine and gastroenterology at McGill University, Croitoru did post-doctoral work with Dr. John Bienenstock at McMaster University, and then joined the Division of Gastroenterology at McMaster in 1992, serving as Training Program Director and Associate Director of the Division. He served as the Chair of the CCFC Medical Advisory Board and helped develop the CCFC IBD Research Institute, and he served as Chair of the Executive Committee until 2008.

Croitoru’s research is focused on IBD: investigating how intestinal inflammation occurs, especially the role of T cell effector and regulatory function in the gut mucosa. His work aims to understand how T cells maintain intestinal homeostasis in health, and the problems in regulatory T cells that allow for the breakdown of these mechanisms. Croitoru is also project leader of the CCC GEM Project (www.GEMPROJECT.ca): a multi-million-dollar prospective cohort study of individuals who are at risk of developing Crohn’s disease. The project explores the genetic, environmental, and microbial factors contributing to Crohn’s disease.
