Brief Biography


Dr. Stiell has recently released a smartphone app! Download "The Ottawa Rules" here for iPhone or Android.

Dr. 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. He has published 302 peer-reviewed papers in very high-impact journals, 19 of which he is listed as first author. He has won many international awards that include election into the U.S. Institute of Medicine.

Dr. Stiell has established the Emergency Research Group within the OHRI which is now comprised of 6 CIHR-funded clinician investigators, 5 international research fellows, and 30 staff. The group currently holds more than 12 million dollars in peer-reviewed funding from CIHR, HSFC, NIH, and others. 

Two emergency medicine research networks have also been established under Dr. Stiell's leadership. OPALS Pre-hospital Group consists of 12 Ontario cities that work together on large pre-hospital resuscitation studies which now works with the Canadian Resuscitation Outcomes Consortium (CanROC), and an informal network of 10 large Canadian teaching hospitals that collaborate on ED studies. Dr. Stiell's tireless dedication to healthcare research has had a major impact on emergency care worldwide, and hopes to continue to do so.
