Defense Threat Reduction Agency

Dr. Ron Hann, a member of the Senior Executive Service (SES), is the the Research and Development Directorate’s Chemical/Biological Technologies Department (RD-CB) director, for the Defense Threat Reduction Agency (DTRA), located on Fort Belvoir, Va. DTRA enables the DoD and U.S. government to prepare for and combat weapons of mass destruction (WMD) and improvised threats and to ensure nuclear deterrence.

Dr. Hann oversees a vibrant science and technology department that works with industry, research universities, other agencies within the U.S. government to research, develop and field revolutionary technologies that address the threats posed by chemical and biological weapons, materials, agents and emerging diseases to our warfighters. DTRA RD-CB also serves as the Joint Science and Technology Office, a member of the Chemical and Biological Defense Program. This office, established in 2003 by Congress, is tasked to develop, coordinate, integrate, execute, and transition DoD chemical and biological science and technology medical and nonmedical programs in response to Joint Requirements Office for Chemical, Biological, Radiological, and Nuclear Defense requirements, the Joint Program Executive Office for Chemical Biological Defense programs, and Chemical and Biological Defense Program Test and Evaluation technology needs.

Dr. Hann received an ROTC scholarship and was commissioned as an officer in 1986; he first enlisted in the U.S. Army Reserve as an Infantryman in 1983.

While in that tour, he helped train, equip, deploy and led site exploitation teams in Iraq in the search for evidence of Saddam Hussein’s WMD program. Following that tour, he earned a doctorate in Organic Synthesis from the University of Virginia; then taught Organic Chemistry at the U.S. Military Academy at West Point.
