Thank you for stopping by! Recognizing the centrality of scientific evidence to a comprehensive Commissioned Corps of the U.S. Public Health Service (USPHS), ours was the fifth Professional Category to be established. The USPHS offers a wide array of career opportunities for Scientist officers, beginning at your call to active duty, and continuing through to your retirement decades later. USPHS Scientists comprise a diverse group of doctoral-level researchers, epidemiologists, clinicians, regulatory experts, program managers and emergency responders. Our Scientists serve across the Federal agencies and around the world to advance the health and safety Mission of the USPHS. Scientists at the Centers for Disease Control and Prevention lead epidemiological surveillance and research programs, we ensure compliance with regulatory requirements and clinical research at the Food and Drug Administration, conduct basic and clinical investigations at the National Institutes of Health, and provide clinical care to service members at Military Treatment Facilities throughout the Department of Defense who have suffered traumatic brain injuries and psychological health conditions. Each of these specialties come together during times of National and international crisis to lead many of the USPHS response activities. Whatever your specialty, you will find an exciting career path that will contribute substantively to the Mission of our Service to protect, promote and advance the health and safety of the Nation.
