The National Nuclear Security Administration (NNSA) has appointed Jay Tilden as associate administrator and Dave Bowman as deputy associate administrator for counterterrorism and counterproliferation, the agency announced Monday.
Most recently Tilden served as acting associate administrator following Steve Aoki’s departure from the position late last year, the announcement said. He previously also worked as deputy associate administrator in the same office, director of the Office of Nuclear Threat Science, intelligence and security advisor to the deputy under secretary for counterterrorism, and director of the counterterrorism division in the Department of Energy’s Office of Intelligence and Counterintelligence. Bowman, who this year has been serving as the acting deputy associate administrator, is now the permanent deputy. He previously worked as deputy director and then director for the NNSA’s Office of Nuclear Incident Response.
