Ambassador-at-Large, Deborah L. Birx, M.D., is the Coordinator of the United States Government Activities to Combat HIV/AIDS and U.S. Special Representative for Global Health Diplomacy. Ambassador Birx is a world-renowned medical expert and leader in the field of HIV/AIDS. Her three-decade-long career has focused on HIV/AIDS immunology, vaccine research, and global health. As the U.S. Global AIDS Coordinator, Ambassador Birx oversees the implementation of the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR), the largest commitment by any nation to combat a single disease in history, as well as all U.S. Government engagement with the Global Fund to Fight AIDS, Tuberculosis and Malaria. Serving as the U.S. Special Representative for Global Health Diplomacy, she aligns the U.S. Government’s diplomacy with foreign assistance programs that address global health challenges and accelerate progress toward: achieving an AIDS-free generation; ending preventable child and maternal deaths; and preventing, detecting, and responding to infectious disease threats. In 1985, Ambassador Birx began her career with the Department of Defense (DoD) as a military-trained clinician in immunology, focusing on HIV/AIDS vaccine research. From 1985-1989, she served as an Assistant Chief of the Hospital Immunology Service at Walter Reed Army Medical Center. Through her professionalism and leadership in the field, she progressed to serve as the Director of the U.S. Military HIV Research Program (USMHRP) at the Walter Reed Army Institute of Research from 1996-2005. Ambassador Birx helped lead one of the most influential HIV vaccine trials in history (known as RV 144 or the Thai trial), which provided the first supporting evidence of any vaccine’s potential effectiveness in preventing HIV infection. During this time, she also rose to the rank of Colonel, bringing together the Navy, Army, and Air Force in a new model of cooperation - increasing the efficiency and effectiveness of the U.S. Military’s HIV/AIDS efforts through inter- and intra-agency collaboration. Then known as Colonel Birx, she was awarded two prestigious U.S. Meritorious Service Medals and the Legion of Merit Award for her groundbreaking research, leadership, and management skills during her tenure at DOD. From 2005-2014, Ambassador Birx served successfully as the Director of CDC's Division of Global HIV/AIDS (DGHA), which is part of the agency’s Center for Global Health. As DGHA Director, she utilized her leadership ability, superior technical skills, and infectious passion to achieve tremendous public health impact. She successfully led the implementation of CDC’s PEPFAR programs around the world and managed an annual budget of more than $1.5 billion. Ambassador Birx was responsible for all of the agency's global HIV/AIDS activities, including providing oversight to more than 400 staff at headquarters, over 1,500 staff in the field, and more than 45 country and regional offices in Africa, Asia, Caribbean, and Latin America. Recognized for her distinguished and dedicated commitment to building local capacity and strengthening quality laboratory health services and systems in Africa, in 2011, Ambassador Birx received a Lifetime Achievement Award from the African Society for Laboratory Medicine. In 2014, CDC honored her leadership in advancing the agency’s HIV/AIDS response with the highly prestigious William C. Watson, Jr. Medal of Excellence. Ambassador Birx has published over 220 manuscripts in peer-reviewed journals, authored nearly a dozen chapters in scientific publications, as well as developed and patented vaccines. She received her medical degree from the Hershey School of Medicine, Pennsylvania State University, and beginning in 1980 she trained in internal medicine and basic and clinical immunology at the Walter Reed Army Medical Center and the National Institutes of Health. Ambassador Birx is board certified in internal medicine, allergy and immunology, and diagnostic and clinical laboratory immunology.
