Doan Dao, M.D. is an Assistant Professor of Medicine, Division of Gastroenterology & Hepatology, Johns Hopkins University School of Medicine.

Dr. Dao’s personal passion and professional commitment is the study of and care for patients with hepatitis B virus (HBV).  He has worked in HBV field including clinical research, basic science training, patient care, and outreach and advocacy programs for more than 12 years, beginning early in medical school when he took two years off to do HBV translational research. His devotion to HBV in part stemmed from the large unmet needs in HBV endemic underserved areas of Africa and Asia. He was born and grew up in Vietnam.

Dr. Dao obtained his post-graduate clinical training in Internal Medicine/Gastroenterology & Hepatology (2012-2019), as part of the Physician Scientist Training Program (PSTP), at UT Southwestern Medical Center, Dallas, Texas. PSTP is a formal mechanism to facilitate and support the development of physician-scientists in academic medicine.
