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. S. Victor Feinman

Dr. Feinman received his MD from the University of Vienna (1948) and then trained in Internal Medicine and Gastroenterology at the Vienna General Hospital (1948-51) and Mount Sinai Hospital in Toronto (1951-53). Since 1953, Dr. Feinman has been a staff physician at the Mount Sinai Hospital where he also serves as Director, Liver Study Unit. Dr. Feinman's clinical and research interest is in viral hepatitis. In 2003, Dr. Feinman was the recipient of the Commemorative Medal of the Queen's Golden Jubilee, the Lifetime Achievement Award of the Canadian Liver Foundation and the Ontario Association of Gastroenterology Award for his contributions to Gastroenterology.

 

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.
 

Dr. Geoffrey Nguyen

Dr. Nguyen is an Associate Professor of Medicine at the University of Toronto and the Institute for Health Policy Management and Evaluation. He is also adjunct faculty at the Johns Hopkins School of Medicine and an adjunct scientist at the Institute for Clinical Evaluative Sciences in Toronto. After graduating from the Johns Hopkins School of Medicine in 2000, he completed residency in Internal Medicine at the Johns Hopkins Hospital in 2003. He then pursued a combined clinical and research fellowship in gastroenterology at Johns Hopkins. He concurrently completed a PhD degree in Clinical Investigation at the Johns Hopkins Bloomberg School of Public Health in 2007 under the auspices of an NIH-sponsored National Research Services Award.  His thesis work focused on racial disparities in clinical outcomes and healthcare delivery in inflammatory bowel disease.

Dr. Nguyen is currently appointed as a Clinician Scientist at the Mount Sinai Hospital. He is the recipient of an AGA Research Scholar Award and two consecutive New Investigator Awards from CIHR and the Canadian Association of Gastroenterology. These career development awards have supported his research endeavors in health services and outcomes and clinical epidemiological studies that complement his clinical interests in inflammatory bowel diseases. The main focus of his research is the impact of IBD specialty care on health outcomes at the population level. Dr. Nguyen's research focuses on using administrative health data to monitor patterns of IBD-related healthcare utilization, its determinants, effect on health quality of life and morbidity, and economic impact.  His research is currently funded from operating grants from CIHR.  As chair of the University of Toronto’s GI Committee for Quality Improvement and Safety, he is also a champion for optimizing quality of care in IBD, especially in the prevention and management of venous thromboembolism.

Dr. Silverberg is currently an Investigator at the Lunenfeld investigating genetic aspects of inflammatory bowel disease. His laboratory is focused on identifying novel susceptibility genes for IBD and to explain the contribution of genes and other biomarkers to its etiology and clinical course. More recently he has expanded his program to study the relationship between serum immune responses, gene regulation and the host microbiome and genetic susceptibility. He has made significant contributions to the discovery of genes related to Crohn’s disease, ulcerative colitis and paediatric IBD.
