Dr. Ian Stiell is a clinical epidemiologist and an emergency medicine physician with a focus on health services research in emergency medicine. He is internationally recognized for his clinical research in emergency care. Dr. Stiell established the Emergency Research Group, comprised of 7 clinician investigators, 6 fellows, and 30 staff and has held or is holding over $25 million in peer-reviewed funding from CIHR, HSFC, NIH. Dr. Stiell ranked highly in receiving a CIHR Foundation Award in 2015 for his program “Improving Care for Emergency Department and Pre-Hospital Patients with Acute and Life-Threatening Conditions”.

Dr. Stiell has created 2 emergency medicine research networks since 1994. 1) The OPALS Pre-hospital Group of 12 cities conducts pre-hospital resuscitation studies and now constitutes one of 10 U.S./Canadian sites in the Resuscitation Outcomes Consortium (ROC). 2) An informal network of 12 Canadian academic hospitals that conduct multicenter studies in the ED.

Dr. Stiell was the first Chair of the Department of Emergency Medicine at U Ottawa (2002) and has since developed this into one of the most productive EM units in Canada. He was the inaugural chair for the Academic Section for the Canadian Association of Emergency Physicians (CAEP) and the current Editor in Chief of the Canadian Journal of Emergency Medicine.

Dr. Sheldon Cheskes is an Associate Professor with the Division of Emergency Medicine, Department of Family and Community Medicine at the University of Toronto, and a scientist at the Li Ka Shing Knowledge Institute at St. Michael’s Hospital in Toronto, Ontario, Canada. He is the Medical Director for the Regions of Halton and Peel with the Sunnybrook Centre for Prehospital Medicine. He is one of the principal investigators for the Canadian Resuscitation Outcomes Consortium (CanROC) and is a recognized international authority in the area of CPR quality and out-of-hospital cardiac arrest resuscitation. Dr. Cheskes has published over 100 manuscripts in high impact journals such as the New England Journal of Medicine, Circulation, CMAJ and Resuscitation that have changed resuscitation practice around the world.

He is the principal investigator of the DOuble Sequential External Defibrillation in Refractory Ventricular Fibrillation (DOSE VF) trial. This study will be the first cluster randomized trial to clinically evaluate two novel therapeutic defibrillation strategies (double sequential external defibrillation and vector change defibrillation) against standard practice for patients remaining in refractory ventricular fibrillation during out-of-hospital cardiac arrest. He is also studying methods to improve public access defibrillation in rural and remote areas through the use of community responder programs and drone delivery of automated external defibrillators.

Dr. Catherine Varner is an Assistant Professor and Clinician Investigator within the Division of Emergency Medicine, Department of Family and Community Medicine at the University of Toronto. She is also a clinician scientist at the Schwartz/Reisman Emergency Medicine Institute at Mount Sinai Hospital in Toronto. She is a member of the Ontario Neurotrauma Foundation Guidelines and Concussion Clinic Standards Committees and also conducts research in pregnancy complications in the emergency department.

Brenton Wong is a fourth year medical student at the University of Ottawa. Prior to medical school, he completed his Bachelor of Health Sciences (Honours) degree at McMaster University. He is interested in emergency medicine, clinical research, and medical education. His current research interests include cardiac arrhythmia management in the Emergency Department, with a particular focus on acute atrial fibrillation and flutter. He is currently working on a meta-analysis evaluating the effect of oral anticoagulation use on thromboembolic events following cardioversion of acute atrial fibrillation and flutter, for which he received the Top Medical Student Abstract Award at CAEP 2020. Outside of medicine, he enjoys playing hockey and golf, cooking, and music.


Dr. Justin Yan (BSc, MD, MSc, FRCPC) is an emergency physician and clinician researcher at London Health Sciences Centre and St. Joseph’s Healthcare London, assistant professor in the Division of Emergency Medicine (EM), Department of Medicine at Western University, and associate scientist at Lawson Health Research Institute in London, Ontario, Canada. During his specialist residency training in emergency medicine (EM) through the Royal College of Physicians and Surgeons of Canada, he completed a Masters of Science in Health Research Methodology from McMaster University, followed by an additional research fellowship at the Ottawa Health Research Institute. Currently, he is the primary EM researcher at Western and leads a team of coordinators, assistants and medical trainees to conduct high-quality research in EM.

Dr. Yan has extensive experience collaborating with other Canadian academic researchers in conducting multicentre studies. His own specific area of interest examines patients who present recurrently for hyperglycemic emergencies, and he has published several manuscripts and presented both nationally and internationally on this topic.

In his spare time, Dr. Yan enjoys international cuisine, physical fitness, and playing with his two dogs, Robbie and Marlee.
