Dr. David Lee Thomas is a professor of medicine at the Johns Hopkins University School of Medicine. He is trained in internal medicine and infectious diseases and cares for patients with chronic viral hepatitis. 

From 2006-2022, Dr. Thomas served as the director of the Division of Infectious Diseases and the Stanhope Bayne-Jones Professor of Medicine. He remains a Professor of Medicine in the School of Medicine and of Epidemiology in the Bloomberg School of Public Health. He is a co-director of the Center for AIDS Research Clinical Core.

He earned his undergraduate degree in chemistry, in 1982, and his medical degree, in 1986, from West Virginia University. He then completed his medical training and residency at Wake Forest University in North Carolina, before coming to Johns Hopkins as a research fellow in infectious diseases. He went on to earn his Master of Public Health at the Johns Hopkins Bloomberg School of Public Health. He joined the faculty at both schools, the School of Medicine in 1993 and Public Health in 1994. 

For his commitment to translating medical research into advances in the care of people living with both hepatitis C and HIV, the American Society of Clinical Investigation named Dr. Thomas to its honor list of physician-scientists in 2001. He also was elected into the American Association of Physicians for which he served on Council. He received a MERIT award from the National Institutes of Health.
