Job title: Assistant Professor
Dr. Chhatwal is an assistant professor at Harvard Medical School and a decision scientist at MGH Institute for Technology Assessment (ITA). His research is centered in decision science, data analytics, outcomes research and health economics. He has over 10 years of experience in developing decision-analytic models to evaluate disease outcomes. He currently leads research in multiple disease areas including hepatitis C, liver cancer, liver transplantation, nonalcoholic fatty liver disease, anal cancer, and opioid and alcohol use disorder.
Dr. Chhatwal is the Principal Investigator of a grant from the National Science Foundation that supports development of advanced data-analytic models to evaluate screening and treatment policies for hepatitis C in the United States, and a grant from the American Cancer Society to identify cost-effectiveness personalized surveillance strategy for hepatocellular carcinoma.
In collaboration with the World Health Organization, Dr. Chhatwal lead development of an online, interactive tool — Hep C Calculator — that evaluates the cost-effectiveness of hepatitis C treatment in 28+ countries. Hep C Calculator allows users to interactively enter local cost data of a country and see the cost-effectiveness results in real-time.
His research on hepatitis C modeling has made a direct impact on defining hepatitis C screening and treatment policies, in the United States as well as elsewhere. His work on the cost and impact new hepatitis C drugs has been featured by The Wall Street Journal, Forbes, NPR, and CNBC. In addition, Dr. Chhatwal has conducted research on breast cancer diagnosis that showed how machine learning and operations research methods can improve biopsy decision-making after mammography exams. This work won multiple awards including a best junior faculty paper and best student paper from the Institute for Operations Research and Management Science.
His research interests also include advancement of decision-analytic methods used for medical decision-making. Dr. Chhatwal regularly teaches methods-oriented workshops at the annual meetings of the Society for Medical Decision Making and International Society for Pharmacoeconomics and Outcomes Research. He serves as a cost-effectiveness and decision analysis editor to the journal Clinical Gastroenterology and Hepatology, and is also an editorial board member of Medical Decision Making.
Prior to joining the ITA, Dr. Chhatwal worked as a health economist for Merck Research Laboratories and was a faculty member at the University of Pittsburgh Graduate School of Public Health and MD Anderson Cancer Center. He received a Bachelor’s Degree in Industrial Engineering from Thapar Institute of Engineering and Technology, India in 2001. He then pursued a Master’s Degree in Industrial Engineering at Iowa State University in 2004, and a PhD in Industrial Engineering, focusing on operations research, at the University of Wisconsin-Madison in 2008. He won 2nd place prize in George Dantzig dissertation award, a prestigious award for the best dissertation in any area of operations research and management science that is innovative and relevant to practice.
