Dr. Kenneth Croitoru
Dr. Kenneth Croitoru joined the Division of Gastroenterology at Mount Sinai Hospital in January 2008 as a Clinician Scientist and is a full Professor of Medicine at the University of Toronto.. He completed medical school at McGill University in 1981 and then trained in internal medicine and gastroenterology from 1982-1986. He went on to do post-doctoral training as an MRC Research Fellow in Mucosal Immunology with Dr. John Bienenstock at McMaster University. On completion of this research training he joined the Division of Gastroenterology at McMaster in 1992 where he went on to serve as Training Program Director and Associate Director of the Division. During this time he developed his research program with funding from the Canadian Institute of Health Research, Canadian Association of Gastroenterology and the Crohn’s and Colitis Foundation of Canada. He held an Ontario Ministry of Health Career Scientist award for 10 years and more recently was one of the first recipients of a 5 year CCFC IBD Research Scientist Award. He served as the Chair of the CCFC Medical Advsiory Board and helped develop the CCFC IBD Research Institute where he served as Chair of the Executive Committee until 2008.
His research is focused on investigating the fundamental mechanisms of intestinal inflammation, in particular the role of T cell effector and regulatory function in the intestinal mucosal in Inflammatory Bowel Disease. These studies will be carried out at the Clinical Sciences Division in the Medical Sciences Building at the University of Toronto, where he is a member of the Institute of Medical Sciences. He is collaborating with other members of the CSD as well as with members of the departments of Immunology and Lab Medicine and Pathobiology. The goal of his work is to understand how T cells function serves to maintain intestinal homeostasis in health and what defects in regulatory T cells allow for the breakdown of these mechanisms. Dr. Croitoru is also Project Leader of, the GEM Project (www.GEMPROJECT.ca) a major clinical study that will be coordinated out of the IBD Research Group at Mount Sinai Hospital. The study is a prospective cohort study of healthy subjects at risk of developing Crohn’s disease. These subjects will be identified by virtue of the fact that they are a sibling of a patient with Crohn’s disease and will examine the Genetic, Environmental and Microbial factors that lead to Cohn’s disease. This is a 5 years study linking every major IBD center from across Canada and has received over $5 million in funding from the CCFC. As a result of these research activities, Dr. Croitoru has achieved both national and international recognition for his IBD research.

Dr. Alvin Newman
I went to medical school at the University of Pittsburgh and I trained in Gastroenterology at Johns Hopkins Hospital from 1969-71 and this was followed by 2 years at the MRC Gastroenterology Unit at Central Middlesex Hospital in London, England. In 1973 I joined the faculty and started my position as gastroenterologist at Mt.Sinai Hospital and I have remained there ever since. My principal interest in practice has been in functional gastrointestinal diseases but I see many different GI problems. For many years I was deeply involved in undergraduate medical education at the University of Toronto and I was Director of Curriculum Development for nearly a decade and I oversaw the introduction of a new curriculum in the early 1990s. Prior to my 65th birthday I was a Professor of Medicine. I am now an Adjunct Professor of Medicine.
