Michelle T. Long, MD, MSc is a physician-scientist with an expertise in Nonalcoholic fatty liver disease (NAFLD), and an Associate Professor of Medicine at Boston University. She completed her clinical training at Massachusetts General Hospital and Boston Medical Center. Dr. Long is the Director of the NAFLD Research Center and the Director of Clinical Research for the Section of Gastroenterology and Hepatology. Her clinical and research interests center on the relationship between NAFLD and cardiovascular disease. Dr. Long is primarily interested in patient-oriented research investigating fibrosis and inflammation in patients with NAFLD and in imaging and risk stratification strategies for hepatic fibrosis. Dr. Long has projects at Boston Medical Center and at the Framingham Heart Study where she is the PI of a study evaluating the prevalence and risk factors for liver fat (steatosis) and fibrosis. In Framingham, she is investigating the clinical and genetic correlates of hepatic steatosis and fibrosis as measured by transient elastography. Dr. Long receives research funding from the NIH (NIDDK), Doris Duke Charitable Foundation, Gilead Sciences, Echosens Corporation, and Boston University. She has expertise in epidemiology, visceral fat, liver imaging including computed tomography, ultrasound, and transient elastography. Dr. Long is also a clinical hepatologist and endoscopist.

Dr. Long is additionally interested in novel therapeutics for NAFLD and Non-alcoholic steatohepatitis (NASH) and runs the clinical trials program for the NAFLD Research Center.

Her other research interests include alcohol-related liver disease, hepatitis C, outcomes in end-stage liver disease/cirrhosis.
