Dr Sun is Clinical Assistant Professor at the University of British Columbia and incoming director of the Severe Asthma Clinic at BC Children's Hospital. He received his Masters in Bioethics and his medical degree from the Cleveland Clinic Lerner College of Medicine, Case Western Reserve University, during which time he was also a Medical Student Research Fellow at the National Institute of Environmental Health Sciences of the U.S. National Institutes of Health (NIH). He completed pediatrics residency at the University of Washington and subspecialty fellowship in pediatric pulmonology (respirology) at Boston Children’s Hospital. His research training, spanning clinical investigation, environmental epidemiology, and exposure science, has been supported by the NIH and the Cystic Fibrosis Foundation (CFF), including being a CFF Scholar in the U.S. Pediatric Scientist Development Program.

Bob’s research program studies how the air we breathe affects children’s lung health and disease, with a focus on indoor air pollution and emerging hazards including wildfire smoke. With his bioethics background, he also maintains an active interest in issues of equity and fairness in medical innovation. After many years away, Bob is excited to return to British Columbia and advance respiratory health for the children of B.C., Canada, and beyond.
