Andrew Petrosoniak

MD, MSc (Med Ed), FRCPC

Associate Scientist, Li Ka Shing Knowledge Institute


Dr. Andrew Petrosoniak is an emergency physician and trauma team leader at St. Michael’s Hospital and an Assistant Professor in the Department of Medicine at the University of Toronto. He has completed a Master of Science in medical education where he focused on the use of in situ simulation (practice in the actual workplace) in procedural skill acquisition.

Dr. Petrosoniak’s field of research includes in situ simulation and simulation-based technical skill acquisition. His work focuses on usability testing and the identification of personnel- and systems-based safety threats within acute care medicine. He is the principal investigator of the TRUST study (Trauma Resuscitation Using in Situ simulation for Team Training) that includes a partnership with human factors experts to evaluate systems and processes during high-stakes trauma simulations.

Dr. Petrosoniak is the Co-Director of the Annual Critical Care Skills Course for the FRCP Emergency Medicine residents designed to enhance skill acquisition for rarely performed and high-stakes technical skills. He regularly lectures and instructs simulation sessions for the EM residency program.

He is an invited speaker both nationally and internationally on the topics of trauma, simulation and procedural skill acquisition.
