Samir C. Grover


Associate Scientist, Li Ka Shing Knowledge Institute


Dr. Samir C. Grover is a Clinician-Educator in the Division of Gastroenterology at St. Michael’s Hospital and an Assistant Professor in Gastroenterology in the Department of Medicine of the University of Toronto, where he serves as the divisional program director. His training in medicine, gastroenterology and therapeutic endoscopy was at the University of Toronto (MD, 2001), and in education was at the Ontario Institute for Studies in Education (OISE; MEd, 2010).

Dr. Grover’s research is in the application of simulation to endoscopy education, particularly in the use of education theory to inform curricular training. Among other areas, his research has demonstrated that curricular approaches to endoscopy simulation are superior to ad hoc training and that training of progressive fidelity and complexity in endoscopy simulation improves transfer to the clinical setting.

His work has informed competencies that are used in gastroenterology residency training programs for endoscopy in Canada. It has also led to the development of the University of Toronto Endoscopic Simulation Course, an award-winning week-long introductory course that prepares entry endoscopic trainees in adult gastroenterology, pediatric gastroenterology and general surgery, for their first procedural rotations in gastroenterology.
