Biography
In his research, Corvera focuses on the mechanisms that underlie inflammation, thickening and scarring in the biliary tract.
Corvera graduated from the University of California, San Diego School of Medicine. He completed a residency in general surgery at UCSF. At Memorial Sloan Kettering Cancer Center in New York City, he completed a clinical fellowship in surgical oncology as well as a fellowship in hepatobiliary surgery.

Research Narrative
Dr. Corvera's scientific research interest is focused on understanding the mechanisms of biliary tract fibrosis and inflammation. More specifically, he is interested in studying the clinical consequences of biliary fibrosis-- mainly cholestatisis. Cholestasis is characterized by impaired bile flow causing a high concentration of bile acids in the liver and the circulation. Prolonged exposure to bile acids in the liver can progress to end-stage liver disease and cirrhosis. In the gastrointestinal tract, the absence of bile flow causes profound local and systemic metabolic disturbances. Dr.Corvera is actively investigating the role of a novel cell surface receptor specific for bile acids that may play a critical role in normal and disease states.
