Jag Chhatwal, PhD

Senior Scientist, Massachusetts General Hospital
and Assistant Prof., Harvard Medical School

Dr. Chhatwal's research is centered in decision science, data analytics, outcomes research and health economics. Dr. Chhatwal has over 12 years of experience in developing mathematical models to inform health policy. For the last several years, he has worked in the area of developing decision-analytic models in liver diseases to inform clinical decisions and health policies. Dr. Chhatwal has collaborated with the Department of Health and Human Services and the World Health Organization (WHO) to policies leading to hepatitis C elimination in the United States and elsewhere. In partnership with the WHO, his groups recently developed an interactive modeling tool, the Hep C Calculator, that allows policymakers from 28 countries to evaluate the cost-effectiveness of hepatitis C treatment in those countries. Dr. Chhatwal’s work has been featured in leading media such as The Wall Street Journal, Forbes, and National Public Radio. He currently serves as a cost-effectiveness and decision analysis editor of Clinical Gastroenterology and Hepatology and is also an editorial board member of Medical Decision Making.
