Assistant Professor, Department of Internal Medicine, Division of Gastroenterology/Hepatology

My research interests focus on the role of epigenetic regulators, specifically involved in histone arginine and lysine methylation and demethylation, in the various aspects of liver disease, particularly in alcohol-associated liver disease, ALD and liver cirrhosis.
