Rescu is dedicated to the advancement of the science of emergency health care delivery in the out-of-hospital setting. Out-of-hospital emergency care delivery is a conjoint municipally and provincially funded system providing care to millions of patients a year, requiring multiple emergency medical services (EMS) systems and thousands of providers throughout the province of Ontario. This research program conducts emergency medical services systems research and has the ability and capacity to conduct large clinical trials.  I conduct systematic reviews and meta-analyses in topics pertaining to acute coronary syndrome and resuscitation, and have established a collaborative network to conduct and publish randomized controlled trials and outcome validation studies in prehospital resuscitation research. I am a National Institute of Health, Canadian Institute of Health Research and Heart and Stroke Canada funded investigator within the Resuscitation Outcomes Consortium.
