Kenneth Croitoru, MDCM, FRCPC

Dr. Kenneth CroitoruDr. Kenneth Croitoru joined the Division of Gastroenterology at Mount Sinai Hospital in January 2008. He completed medical school at McGill University in 1981 and 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 Advisory Board and helped develop the CCFC IBD Research Institute where he served as Chair of the Executive Committee until 2008.

Dr. Croitoru joined the Department of Medicine at Mount Sinai Hospital as a Clinician Scientist in 2008 and is appointed to the Lunenfeld-Tannenbaum Research Institute. He is also a full Professor of Medicine at the University of Toronto, a member of the Institute of Medical Sciences and has a cross-appointment in the Department of Immunology.

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 (IBD). The goal of his work is to understand how T cells function 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 ( a global clinical study that is coordinated out of the IBD Research Group and Zane Cohen Center at Mount Sinai Hospital. The study is a prospective cohort study of healthy subjects at risk of developing Crohn's disease. That will explore the Genetic, Environmental and Microbial factors that lead to Cohn's disease. This study has had over $15 million in funding from Crohn's Colitis Canada, CIHR and the Helmsley Charitable Trust.

Tae Hart, PhD

Associate Scientific Staff

Tae HartDr. Tae Hart’s research centers on psychological factors associated with adjustment to illness in chronically-ill individuals and their spouses/partners. Primarily, Dr. Hart’s work has investigated quality of life, psychological distress, and symptom burden in patients who have been diagnosed with colorectal cancer.  Dr. Hart currently has a grant funded by the Canadian Institute of Health Research to examine physical and psychological health and quality of life in long-term survivors of colorectal cancer who are participants in the Ontario Familial Colorectal Cancer Registry.  Dr. Hart has expanded her program of research to examine the psychological impact of having Lynch syndrome and factors involved in managing risks associated with Lynch syndrome as well as other familial cancers (i.e., familial gastric cancer).

Zane Cohen, M.D., F.R.C.S.(C)

Director - Zane Cohen Centre for Digestive Diseases (ZCC)
Colorectal Surgeon

Dr. Zane CohenZane Cohen obtained his MD degree in 1969 at the Faculty of Medicine, University of Toronto and following this he did his general surgical residency in the Gallie Program at the University of Toronto. During this time he spent two years doing transplantation immunological research with Dr. Rudy Falk, and following his general surgical training he spent two years in the United Kingdom. One clinical year was at St. Mark’s Hospital for Diseases of the Colon and Rectum, and another research year was done at the London Hospital in London, England in transplantation immunology.

Zane returned to join the staff of Department of Surgery at the University of Toronto and the Division of General Surgery at the Toronto General Hospital in 1977 as a Lecturer. Over the next 12 years he rose through the ranks to become a Professor of Surgery in the Department of Surgery at the University of Toronto.

In 1990 Zane Cohen moved to Mount Sinai Hospital to take up the position of Surgeon-in-Chief. He remained as Surgeon-In-Chief until June 30, 2006. In 1999, he was appointed as Chairman of the Division of General Surgery at the University of Toronto, an appointment which he now held until June 30, 2009. He has served as the Chairman of the Promotions Committee for the Department of Surgery from 1996 to 2001. He is an active member of the Senior Advisory Committee and the Finance Committee of the Department of Surgery.

Zane Cohen’s clinical interests have been almost entirely in the area of colon and rectal surgery. Zane had the opportunity to train with Professor Nils Kock on three separate occasions, and developed and brought to the university innovative surgical techniques which have helped thousands of patients afflicted with Inflammatory Bowel Disease and colorectal cancer. He has a specific interest in sphincter saving operations, and introduced the procedures of the Kock Pouch and the Pelvic Pouch techniques at the University of Toronto to patients with ulcerative colitis.

He also popularized the use of the double-staple technique for low anterior resections within the Division of General Surgery. Zane Cohen was the Co-Founder, along with Philip Gordon, of the Canadian Society of Colon and Rectal Surgeons and served as its second president. He was instrumental in developing a Colon and Rectal Training Program at the University of Toronto, amongst several of the teaching hospitals. His initial research interests were in the field of intestinal transplantation, and he, along with Dr. Bernard Langer, carried out the first human intestinal transplantation in the cyclosporine era.

Zane Cohen has authored over 230 manuscripts and book chapters, mainly in the area of Inflammatory Bowel Disease and colorectal cancer and intestinal transplantation. He has held peer reviewed research grants from all of the major granting agencies for his initial work in intestinal transplantation and his subsequent research work related to outcomes in inflammatory bowel disease. Zane has been an invited speaker world wide, he has an international reputation, and he is held in esteem by many of the general surgical residents, as well as the colorectal residents/fellows that he has trained.

He has been recognized for his achievements on many occasions, most recently by the Finkelstein Award for Continued Excellence in Research in Inflammatory Bowel Disease, the Mentors Award from the American Society of Colon and Rectal Surgeons in 2004, and the Colin R. Woolf Award for Excellence and Innovation in Course Coordination in 2005 for the General Surgery Update Course. He has been honored by Ben Gurion University of the Negev with a gala affair in Toronto attended by over 800 people.

Most recently, he has been again honoured with the naming of the Zane Cohen Centre for Digestive Diseases. Within this centre are 24 clinical researchers from medical students to surgical and medical trainees, as well as faculty, who are all involved in IBD and colon cancer research. The Dr. Zane Cohen lectureship has recently been initiated by a group of his colleagues.
