Dr. Ben Tsang is Senior Scientist, Ottawa Hospital Research Institute and Professor of Obstetrics & Gynaecology and Cellular & Molecular Medicine, University of Ottawa. He completed his undergraduate training in chemistry at Bemidji State University, received MSc (Biochemistry) from the University of Iowa, and Ph.D. (Pharmacology) from the University of Ottawa. In 1980, Dr. Tsang joined the University of Ottawa as the Director, Reproductive Biology Unit and initiated a research-intensive academic program in the Department of Obstetrics and Gynaecology. He served as Associate Chair (Research) of the Department, and developed a multi-disciplinary reproductive health research program in Ottawa.  As the Director of Research of the Ottawa Civic Hospital, he played a central role in research development at the Loeb Research Institute.

Research interests

Professor Tsang is an internationally recognized ovarian biologist, who has the insight and ability in bringing fundamental research into the clinical context. His team of basic scientists and clinical investigators address important reproductive health issues, including female infertility, ovarian cancer and pregnancy complications. Dr. Tsang’s research program covers the broad area of cell fate regulation in women’s reproductive health. He and his team are examining the cell signaling pathways involved in the regulation of ovarian cell survival and apoptosis and have defined the basic mechanisms governing normal ovarian follicular growth and offered important insights into the pathophysiology of various ovarian disorders associated with infertility, including polycystic ovarian syndrome. In addition, his research on the molecular and cellular basis of chemoresistance in ovarian cancer has provided key information for the development of new therapy for chemoresistant ovarian cancer, a most lethal cancer in women.
