CAPT Singer is a U.S. Public Health Service (PHS) officer assigned to the National Institute of Allergy and Infectious Diseases (NIAID) and detailed to the Uniformed Services University (USU) as an Associate Professor in the Department of Preventive Medicine and Biostatistics (PMB).

Dr. Singer enlisted in the Army in 1985 and was assigned to the 82nd Airborne Division, Fort Bragg, NC until 1989. Transferring to the National Guard, he completed his undergraduate studies at the University of Georgia in 1991. He was commissioned as an Army 2LT in July 1991, matriculated to the Uniformed Services University and received his medical degree in 1995.

Following completion of a transitional internship at Tripler Army Medical Center in 1996, (then) CPT Singer was assigned to 3rd Battalion, 3rd Special Forces Group (Airborne), Fort Bragg, NC. As the Battalion Surgeon, he deployed on training and contingency deployments within the U.S. and 14 overseas missions to the African continent, where he directed or supported humanitarian civic assistance projects, medical training, military and peacekeeping skill training and de-mining activities as individual JCETs or elements of larger exercises. Most impactful on Dr. Singer was the effect the HIV epidemic was having on African militaries, observing 25-30% of the soldiers trained were dying by the next six-month training iteration.

In 2000, Dr. Singer was assigned to the Walter Reed Army Institute of Research (WRAIR), completing a Master’s in Public Health from the Johns Hopkins School of Public Health in 2001 and General Preventive Medicine Residency in 2002. Subsequently assigned to the Division of Retrovirology at the WRAIR, he immediately deployed to Uganda and Kenya in support of the division’s HIV research, and in 2003 was assigned to the 101st Airborne Division for the invasion of Iraq.

In 2004, Dr. Singer was detailed to the U.S. Embassy in Abuja, Nigeria as the Embassy’s DOD representative to the President’s Emergency Plan For AIDS Relief (PEPFAR), working closely with the Centers for Disease Control and Prevention (CDC) and U.S. Agency for International Development (USAID). Simultaneously he was co-directing the implementation of PEPFAR and exploratory HIV research with the Nigerian military. In 2006 his Army commission was transferred to the PHS; under NIAID, he continued the NIAID-WRAIR/ PEPFAR-research collaboration in Nigeria by direct assignment to the Embassy as Health Attaché (Defense) and Director, DOD HIV Program (Nigeria). His accomplishments include implementation of annual PEPFAR budgets that grew from $75M in 2004 to $486M in 2011, annual HIV research budgets of $1.5M, and growth of the Nigerian military’s budget contributions to 30% of the U.S.; though, most proudly and prominently was the hundreds of thousands of Nigerians tested for HIV and placed on lifesaving anti-retroviral treatment.
Since his CONUS reassignment in 2011, he has served in the Office of Secretary for Defense (Global Strategic Affairs)/(Countering Weapons of Mass Destruction), and since 2012, at the Division of Preventive Medicine, Uniformed Services University as an Associate Professor in a variety of teaching, service and research activities including the Department’s Vice Chair for Medical Education, PHS Company Commander, and Chair, Sub-Committee #2, School of Medicine Admissions Committee.

Dr. Singer is board certified in General Preventive Medicine, has authored/co-authored 23 manuscripts and book chapters. His awards include the Distinguished Service Medal, Meritorious Service Medal (1OLC), Air Medal and the PEPFAR 2011 Joe Haydon Award.
