Siegfried S. Hecker, a senior fellow and emeritus director of Los Alamos National Laboratory, will join CISAC as a visiting professor in 2005-2006. He will teach undergraduates and pursue research and policy advising on nuclear proliferation and the security of nuclear weapons stockpiles.

As the Los Alamos director, Hecker advised the U.S. Congress on nuclear security challenges created by the Soviet Union's dissolution. He worked with Russian counterparts to consolidate nuclear weapons from four former Soviet states and to implement new security measures agreed to under the Nunn-Lugar Cooperative Threat Reduction program.

"Russia is the key link to fighting nuclear proliferation," Hecker said. He continues to advise Congress members and staff and to work closely with the Russian Academy of Sciences and the Russian Ministry of Atomic Energy on several cooperative threat reduction programs.

On his arrival this fall, Hecker will be one of two former national lab directors at CISAC. Emeritus Professor Michael M. May formerly directed Lawrence Livermore National Laboratory.

Science magazine announced Hecker's CISAC appointment in its Aug. 5 issue.

Two of the 10 Stanford University undergraduates who completed CISAC's Interschool Honors Program in International Security Studies this year earned awards for their theses.

Sheena Elise Chestnut, a political science major, received a Firestone Medal for her thesis, "The 'Sopranos State'? North Korean Involvement in Criminal Activity and Implications for International Security." The Firestone Medal recognizes the top 10 percent of Stanford University's undergraduate honors theses.

Jessica McLaughlin, a management science and engineering major, received the William J. Perry Award for her thesis, "A Bayesian Updating Model for Intelligence Analysis: A Case Study of Iraq's Nuclear Weapons Program." The Perry Award recognizes excellence in policy-relevant research in international security studies.

In a June graduation ceremony outside Stanford University's Encina Hall, CISAC faculty member Mariano-Florentino Cuéllar, CISAC Postdoctoral Fellow Tonya L. Putnam, and CISAC Co-Director Scott D. Sagan presented students with certificates and thesis awards.

At a CISAC Directors' Seminar on June 1, Chestnut and McLaughlin presented their award-winning theses to an audience of 50 fellow students, faculty members and guests. Chestnut also gave a special seminar at CISAC in May, hosted by APARC and the Preventive Defense Project at CISAC.

The names, majors and thesis titles of eight others who completed the CISAC honors program are

Zack Cooper, public policy, Roman and British Experiences with Maritime Piracy and Implications for Combating Terrorism Today

Nina Hsu, political science, Chinese Assistance in the Pakistani Nuclear Program

Sohan Japa, biomechanical engineering, A Path to Peril: Understanding the Technical Hurdles of Biological Weapon Production

Bradley Larson, political science, Soft Power: US Foreign Aid Post-9/11

Frances Lewis, international relations, The Yellow Light Reactor: An Explanation of the Stop and Go Progress at Bushehr

Victor Marsh II, international relations, A Responsibility to Consult? Local Policy Ownership During Transitional Governance

Christopher Williams, physics, Closing the Nuclear Fuel Cycle: A Component Based Analysis of Options for Spent Fuel Management"

Ming Zhu, international relations, Power and Cooperation: Understanding the Road Towards a Truth Commission

Begun in 2000 to help develop the next generation of security specialists, CISAC's honors hrogram accepts 12 to 14 Stanford undergraduates each year, from any disciplines. Those selected attend a two-week CISAC honors college in Washington, D.C., complete an internship with a security-related organization, attend a year-long core seminar on international security research and produce an honors thesis with policy implications for international security. After fulfilling their individual department course requirements and completing the honors program, participants graduate in their major with an honors certificate in international security studies.

After five years as CISAC's co-director, Christopher F. Chyba left Stanford University to become the co-director of the Program on Science and Global Security and a professor of astrophysical sciences and international affairs at the Woodrow Wilson School at Princeton University.

"We thank Chris for his superb leadership and look forward to continued collaboration with him on biological security and nuclear nonproliferation," said Scott D. Sagan, who served as co-director with Chyba and now directs the center. Chyba accepted an appointment as a CISAC affiliate.

At Stanford, Chyba was also an associate professor in the Department of Geological and Environmental Sciences, and he held the Carl Sagan Chair for the Study of Life in the Universe at the SETI Institute in Mountain View, Calif.

Committed to providing policy-relevant research on international security from both social science and science perspectives, CISAC is traditionally co-directed by a social scientist and a scientist or engineer. The center is conducting a worldwide search for a scholar with scientific expertise to join Sagan, a political science professor, in leading its research, teaching and policy advising programs.
