Timothy R. Sterling, MD, received his medical degree from the Columbia University College of Physicians & Surgeons, residency training in internal medicine at Columbia-Presbyterian Medical Center, and fellowship training in infectious diseases at Johns Hopkins Hospital.  He is the Director of the Vanderbilt Tuberculosis Center and Director of Epidemiology Research in the Division of Infectious Diseases. Dr. Sterling’s research interests are focused on the epidemiology and treatment of tuberculosis and HIV. Particular areas of interest include latent tuberculosis infection, drug resistance in M. tuberculosis (including multidrug resistance and fluoroquinolone resistance), and HIV-related tuberculosis. He also has an interest in the immunogenetic predisposition to TB, particularly extrapulmonary disease. He conducts clinical trials and observational cohort studies of people with HIV and tuberculosis, including in the Tuberculosis Trials Consortium (TBTC), the North American Cohort Collaboration on Research and Design (NA-ACCORD), the Caribbean Central and South America Network for HIV Epidemiology Research (CCASAnet), and the Regional Prospective Observational Research in Tuberculosis (RePORT), collaborating with investigators in Brazil and South Africa. The above ongoing research studies in the United States, Brazil, Peru, and South Africa are funded by the U.S. Centers for Disease Control and Prevention and the National Institutes of Health.
