Bio

Dr. Martin Urner graduated from the University of Zurich Medical School and completed his specialty training in Anesthesiology and Intensive Care Medicine at the Zurich University Hospital in Switzerland. He is currently working as an attending physician in the Medical/Surgical Intensive Care Unit at the Toronto General Hospital and is an Assistant Professor and early career researcher of the Department of Anesthesiology & Pain Medicine at the University of Toronto. Dr. Urner's Ph.D. thesis in Clinical Epidemiology and Health Care Research at the Institute of Health Policy, Management, and Evaluation (IHPME) of the University of Toronto investigated the association between time-varying intensity of mechanical ventilation and outcomes of patients with acute respiratory failure. As an intensivist and anesthesiologist, Dr. Urner pursues an academic career as a clinician-scientist in critical care medicine with a special expertise in causal inference and prediction modeling using large longitudinal datasets for research in physiology, anesthesiology, and critical care medicine. As of this writing, his research work has resulted in 58 publications and three patent applications and has been funded with a total amount exceeding $1,000,000 CADs. During his Ph.D. thesis work in Clinical Epidemiology and Health Care Research at IHPME of the University of Toronto, Dr. Urner developed expertise in Joint Models for Longitudinal and Survival Data, Causal Inference using g-methods, and Causal Mediation Analysis. The results of his thesis work were successfully published in high impact journals – The Lancet Respiratory Medicine and The BMJ. A Vanier Canada Graduate Scholarship has supported Dr. Urner's thesis work.
