Research Synopsis


Dr. Friedman has published in several areas of education and simulation. The focus of his current research is the ability to challenge authority across hierarchy gradients. Previous studies involved skills assessment through simulation, the effect of technical skills on non-technical skills and the impact of simulation on skills acquisition. These studies were funded by grants from the Anesthesia Patient Safety Foundation (first non US physician to win the award), Royal College of Physicians and Surgeons, Physicians’ Services Incorporated Foundation and Canadian Anesthesiologists’ Society as well as several Research Merit Awards from the University of Toronto.
