Welcome to OAR

The Office of AIDS Research (OAR) coordinates HIV/AIDS research across the National Institutes of Health (NIH). The NIH provides the largest public investment in HIV/AIDS research globally.

As HIV crosses nearly every area of medicine and scientific investigation, the response to the HIV pandemic requires a multi-Institute, multidisciplinary, global research program. OAR provides scientific coordination and management of this research program.

Leadership from OAR and the National Institute of Allergy and Infectious Diseases held an “Ask the Experts” session, giving attendees an opportunity to learn and ask questions about the NIH HIV research program. Learn about on-site NIH activities.
