About Me

Dr. Constantine (Dean) Karvellas is an Associate Professor of Medicine (Critical Care Medicine and Gastroenterology/Hepatology) at the University of Alberta and an Adjunct Professor in the School of Public Health Sciences. He has been an attending intensivist in the E. Garner King General Systems Intensive Care Unit since 2009 and is involved with the Liver Transplant program as a Hepatologist. Dr. Karvellas is the only Canadian co-investigator in the NIH-funded United States Acute Liver Failure study group (US ALFSG). He is also a member of the Society of Critical Care Medicine (SCCM) Liver management task force. Dr. Karvellas’ publications reflect his interests in acute liver failure (ALF), acute on chronic liver failure (ACLF), liver transplantation and extracorporeal liver support.
