Gastroenterologist

Dr. Geoffrey NguyenDr. Nguyen is Professor of Medicine at the University of Toronto and the Institute for Health Policy Management and Evaluation.  He is also 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.


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 CIHR Embedded Clinician Researcher Award. These career 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.  He is the national lead for the Promoting Access and Care through Centres of Excellence (PACE) a national network dedicated to improving access and quality of care for patients with IBD.  He is also Chair of the CINERGI group, a Canadian-wide collaborative network of IBD centres focused on quality improvement initiatives.  He has spearheaded the Choosing Wisely campaign in IBD and was the lead author on several North American clinical practice guidelines in IBD.  His is a recipient of the Canadian Association of Gastroenterology’s Young Investigator Award and the University of Toronto Department of Medicine Award for Quality and Innovation.  As part of the PACE program, he and his research team have pioneered the use of telemedicine to improve access to IBD care to underserviced regions of Ontario.
