Dr. Delbert R. Dorscheid

Dr. Dorscheid is a member of the Divisions of Critical Care Medicine and Respirology at St. Paul ‘s Hospital, one of the University of British Columbia hospitals. He arrived in Vancouver on July 1, 2000 after being recruited from the University of Chicago. Dr. Dorscheid attends in the medical intensive care unit at St. Paul ‘s and is a researcher at the HLI. As a young physician-scientist, he leads an active research group investigating the role of the airway epithelium in the genesis of inflammatory airways diseases. The research program studies the role for inappropriate injury-repair cycles in the development of both chronic diseases such as asthma and acute illnesses like ALI/ARDS. Specific projects include the role of glucocorticoid-induced airway epithelial cell apoptosis, novel glycoproteins and the glycomics involved in the repair of an injured epithelium, and the expression of FasL as an immune barrier for the airway.

Dr. Dorscheid obtained his MD and PhD degrees from McGill University in Montreal. He graduated from Medicine in 1993 and two years later he defended his PhD thesis in Experimental Medicine. He moved onto Chicago where at the University of Chicago he completed his Internal Medicine residency and subsequently a fellowship in Pulmonary and Critical Care Medicine. During his time at the University of Chicago, he completed post-doctoral research with Dr. Steve White. After one year on the Faculty at the University of Chicago, he relocated with his family to Vancouver to take a position in Critical Care Medicine at UBC.
