Dr. Carl W. Dieffenbach is the Director of the Division of AIDS at the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health. Under his leadership, the Division supports a global research portfolio to advance biological knowledge of HIV/AIDS, its related co-infections, and co-morbidities. With the ultimate goal of creating an “AIDS-free Generation,” the Division develops and supports the infrastructure and biomedical research needed to: 1) halt the spread of HIV through the development of an effective vaccine and biomedical prevention strategies that are safe and desirable; 2) develop novel approaches for the treatment and cure of HIV infection; 3) treat and/or prevent co-infections such as tuberculosis, and co-morbidities of greatest significance; and 4) foster partnerships with scientific and community stakeholders to develop and implement effective interventions. Dr. Dieffenbach received his bachelor’s degree in biochemistry from the University of Maryland in 1976 and his Ph.D. in biophysics from The Johns Hopkins University in 1984.
