ing particle transport. This effort continued after he became a code developer in the secondary-design division at Lawrence Livermore National Lab, and it has continued and broadened during 15 years on the faculty at Texas A&M University. Dr. Adams’s contributions include improved discretization methods, theoretical analysis of the behavior of various methods in various limits, theory of iterative methods, and improved iterative methods. In recent years he has focused on efficient large-scale coupled-physics simulations and on assessing the predictive capability of such simulations. He led a project that developed and continues to improve the PDT code (3D massively parallel deterministic transport), and he directed Texas A&M’s Center for Large-Scale Scientific Simulations. This center focuses on coupled-physics simulations with emphasis on quantitative assessment of predictive capability. Dr. Adams has served on panels and committees that review and advise the NNSA labs and DOE on matters including stockpile stewardship and the role of advanced scientific computing (ASC) in the weapons program.
John Cornwall received his A.B. from Harvard and his Ph.D. from the University of California, Berkeley. After postdoctoral positions at CalTech and the Institute for Advanced Study, he became a faculty member at UCLA, where he does research in elementary particle theory; later he became a professor of science and policy analysis at the Pardee RAND Graduate School in Santa Monica. He is the author of more than 130 refereed publications and contributions to books and coauthor of a roughly equal number of unpublished assessment and review reports in numerous technological areas. He has been a visiting professor at many institutions in the United States and abroad. For many years he was a consultant to the Space Sciences Laboratory of the Aerospace Corporation, where he did research on the magnetosphere and the aurora. He has served on the Defense Science Board and is a consultant to the Los Alamos and Livermore National Laboratories and to the Institute for Defense Analyses. He serves as chairman of the Defense and Nuclear Technology Review Committee of the Lawrence Livermore National Laboratory as well as chairman of the Predictive Science Panel reviewing strategic computing at Los Alamos and Livermore and is a member and for some years was vice chairman of JASON, advising the government on subjects such as ballistic missile defense, ultrasound technology, and the human genome project, among others. He has authored several works on, and testified to Congress concerning, ballistic missile defense, including as coauthor of the report Countermeasures of the Union of Concerned Scientists. He has been an adviser to, and lecturer in, the Public Policy and Nuclear Threats program of the Institute for Global Conflict and Cooperation at the University of California, San Diego. He is a fellow of the American Associa-
