  • Jayan Nagendran

  • MD, Ph.D, FRCSC  Vice President & Director of Clinical Investigation

Dr. Jayan Nagendran is a cardiac surgeon clinician-scientist with an interest in end-stage lung disease and lung transplantation. The focus of his lab and clinical research is on the development and advancement of ex-vivo lung perfusion. He attended undergraduate and medical school at the University of Alberta, completing his MD in 2001. He joined the residency program in Cardiac Surgery at the University of Alberta from 2001-2009, and completed a Ph.D in Experimental Medicine during that time (2005-2008). After completing his cardiac surgical residency, Jayan sub-specialized in cardiothoracic transplantation surgery at Stanford University from 2009 to 2011. Dr. Nagendran’s pioneering roles in ex-vivo lung perfusion in Canada includes performing the first portable clinical ex-vivo lung perfusions in Canada. He created the second clinical ex-vivo lung perfusion program in Canada. He is the sole Canadian investigator of the largest international randomized controlled clinical trial examining the efficacy of ex-vivo lung perfusion compared to the standard of care (cold storage), the INSPIRE clinical trial. Dr. Nagendran is an Assistant Professor in the Department of Surgery and the Director of Research for the Division of Cardiac Surgery at the University of Alberta since 2011.
