MD, FCAI, MA

Co-Director, Critical Illness and Injury Research Centre

Biography

Dr. Laffey is Anesthesiologist-in-Chief at St Michael’s Hospital, Toronto, Co-Director of the Critical Illness and Injury Research Centre at the Keenan Research Centre, St. Michael’s hospital. He is a Clinician Scientist at the Keenan Research Centre, and Professor of Anesthesia, Critical Care and Physiology at the University of Toronto. His research is focused on ARDS, particularly the mechanisms underlying ventilation induced lung injury. He has a longstanding interest in the effects and mechanisms of hypercapnic acidosis in ARDS and sepsis. His current research focus is the investigation of the therapeutic potential of cell therapies for ARDS.
