David Q.H. Wang, M.D., Ph.D.

Professor, Department of Medicine (Gastroenterology & Liver Diseases)

Areas of Research: Cholesterol and bile acid metabolism in the liver, bile, intestine and plasma; Cholelithiasis; Intestinal lipid absorption; Nonalcoholic fatty liver disease; Alcoholic liver disease; cholestasis.

Professional Interests

Dr. Wang has an active research interest in the molecular and genetic mechanisms of cholesterol homeostasis and the pathophysiology of cholesterol-related diseases. The long-term objectives of his research are (i) to identify gallstone (LITH) genes and investigate their genotypes and phenotypes in mice and humans, as well as elucidate the molecular, cellular, genetic and physical-chemical mechanisms of cholesterol gallstone disease at a fundamental level; (ii) to study molecular, cellular, genetic and physical-chemical factors that determine intestinal absorption efficiency of cholesterol and fatty acids; and (iii) to investigate the pathophysiology of the metabolic syndrome with a special focus on the relationship between insulin resistance and nonalcoholic fatty liver disease, and examine the pathogenesis of alcoholic liver disease and obesity, as well as explore novel approaches for the prevention and treatment of these lipid-related hepatobiliary and gastrointestinal diseases.
