Louise Sun, MD, is a staff anesthesiologist at the University of Ottawa Heart Institute and an Assistant Professor of Anesthesiology and Epidemiology at the University of Ottawa. Dr. Sun also holds a full status Adjunct Scientist position at the Institute for Clinical Evaluative Sciences (ICES). Dr. Sun is the Director of Team Soleil at UOHI.
Dr. Sun received her medical degree from McMaster University in 2008. She completed her Anesthesiology Residency at the University of Ottawa in 2013 and received her Master of Science in Epidemiology from Harvard University that same year. As a trainee, Dr. Sun received awards at several research competitions and was published in high impact journals such as JAMA Internal Medicine and Anesthesiology.
Dr. Sun completed a fellowship in Cardiac Anesthesia and Research at Toronto General Hospital in 2014 and joined the Heart Institute in early 2015. She was appointed to ICES faculty that same year.
Dr. Sun’s population and precision-based research program in heart failure and cardiac surgery outcomes is supported by the Canadian Institutes of Health Research, the University of Ottawa and the UOHI ORACLE Strategic Plan. Her work has been highlighted by international media and featured as “article of the month” (Anesthesiology 2018), top 3 most cited articles in Anesthesiology (2018), and top 20 most cited articles in Anesthesiology (2017). She is invited to provide cardiovasular health-related commentaries on national channels such as CTV News, and collaborates with regional health authorities to evaluate current models health care delivery.
Dr. Sun has received awards at the Canadian Anesthesiologists’ Society Residents Research Competition (2012 and 2013), was named a top reviewer for the Annals of Internal Medicine (2015), and has been selected as a finalist at the upcoming American Heart Association’s Vivien Thomas Young Investigator Award (2018).
