Laurie Morrison


Scientist, Li Ka Shing Knowledge Institute


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.
