The Naval Health Research Center (NHRC) optimizes the operational readiness and health of our armed forces by conducting research, development, testing, and evaluation to inform Department of Defense (DoD) policy. We have been designated the DoD Deployment Health Research Center since 1999. We conduct science that spans the spectrum from physical readiness to joint medical planning, to wounded warrior recovery and behavioral health interventions, all focusing on the health, readiness, and well-being of our nation’s military members and their families. We conduct research that is operationally relevant and driven by fleet requirements. Our core research areas include Operational Readiness and Health, Military Population Health, and Operational Infectious Diseases. We are one of eight laboratories affiliated with the Naval Medical Research Center in Silver Spring, Maryland, within the U.S. Navy Bureau of Medicine and Surgery. Together, we support military mission readiness with research and development that delivers high-value, high-impact solutions to the health and readiness challenges our military population faces on the battlefield, at sea, on foreign shores, and at home.



To optimize operational readiness and warfighter health by informing DoD policy through research excellence.


To be the premier deployment health research center for the DoD.


NHRC’s team includes researchers and scientists whose expertise includes physiology, microbiology, biomedical engineering, psychology, epidemiology, and software engineering. Our staff is a mix of active duty service members, federal civil service employees, and contractors who are dedicated to our vision of being the DoD’s premier operational health research center.


We are located aboard Naval Base Point Loma in San Diego, California, with access to more than 95,000 uniformed service members, world-class universities, industry leaders, Naval Hospital Camp Pendleton, Naval Medical Center San Diego, and Navy Medicine West. Housed in 24 historic WWII-era military barracks, our San Diego location is ideal, placing us in proximity to a variety of potential research populations.
