Dr. Choi became the director of the Clinical Research Unit in the Department of Anesthesia at Sunnybrook Health Sciences Centre in 2014 and an affiliate scientist at Sunnybrook Research Institute. He obtained his medical degree from the University of Western Ontario (2005), completed anesthesiology at the University of Toronto (2010), subspecialty training in regional anesthesia (2011) as well as an MSc in Health Research Methodology (2014). He is currently a staff anesthesiologist at Sunnybrook Health Sciences Centre (2011). His current research interests include examining optimal methods of providing superior post-operative analgesia with regional techniques and initiating a program to examine cognitive changes after major surgery.  In addition to his own research program, he collaborates on multi-centre trials with internationally recognized investigators. 

Dr. Choi has been awarded over $350,000 in competitive, peer reviewed, grants as a principal investigator. He is a co-investigator on several major, international peer-reviewed grants totaling $14 million.  He has also authored/co-authored 20 peer reviewed manuscripts and is a consultant reviewer for Regional Anesthesia and Pain Medicine. Internationally, he has been invited faculty at the American Society of Regional Anesthesia and Pain Medicine Annual Meeting.
