Before coming to Harvard , Bunn served as an adviser to the White House Office of Science and Technology Policy from 1994-1996 . Bunn directed the secret 1995 study on nuclear security from the President ’s Council of Advisors on Science and Technology ( PCAST ) . This study served as the basis for Presidential Decision Directive 41 ( 1995 ) which established U.S. government policies for securing nuclear materials . From 1992-1996 , Bunn held a position as a study director at the National Academy of Sciences . During this time , he directed Management and Disposition of Excess Weapons Plutonium and this study became the foundation for U.S. government policy on plutonium disposition . ( The creation of what is now the Office of Materials Disposition was announced the day after the report was released . ) Bunn initially suggested and helped coordinate the Nuclear Threat Initiative ’s $ 1.2 million gift to the International Atomic Energy Agency 's nuclear security programs , which became the founding gift of the Nuclear Security Fund . He developed the concepts of “ cold standby ” and “ warm standby ” for Iran ’s centrifuges when various forms of “ suspension ” of Iran ’s program were being discussed and co-authored compromise proposals for resolving the dispute over Iran ’s program with former Iranian deputy foreign minister Abbas Maleki . Bunn and his colleague Anthony Wier were the first to suggest a four-year effort to secure nuclear material worldwide , a goal that was ultimately agreed to at the 2010 Nuclear Security Summit . Bunn , Wier , and John Holdren , formerly President Obama ’s science advisor , first proposed combining U.S. efforts to convert research reactors and remove HEU into a single program , which became the Global Threat Reduction Initiative
