Neil A Chapman Editor

Charles B. Connor is a Professor and Chairman of the Geology Department at the University of South Florida. He has worked on assessment of volcanic hazards at nuclear facilities since 1992, in association with the US Nuclear Regulatory Commission, the International Atomic Energy Agency (IAEA), and the Nuclear Waste Organization of Japan. These professional activities have included developing the US Nuclear Regulatory scientific program for assessment of volcanic hazards at Yucca Mountain, Nevada, chairing of the committee to develop IAEA safety guidance for nuclear power plants, and developing safety guidelines for nuclear installations in Japan. In addition, he served on the US National Research Council commission to review the US Geological Survey volcanic hazards program for the National Academy of Sciences. Neil A. Chapman is Chairman, ITC School of Underground Waste Storage and Disposal, Switzerland; Research Professor of Environmental Geology, Department of Engineering Materials, University of Sheffield; Programme Director, Arius Association, Switzerland; and an independent consultant. He has worked for more than thirty years on the scientific and strategic issues of the nuclear industry and radioactive wastes, for industrial, governmental and international organisations and agencies worldwide. This has involved participation in many national and international advisory committees, in the management of internationally funded projects and as a visiting expert. He is currently Chairman of the INSITE site investigation overview group for the Swedish regulatory authority, SSM, and a member of the International Technical Advisory Committee (ITAC) of the Japanese radioactive waste management organisation (NUMO). Laura J. Connor is a computational scientist and Research Associate in the Department of Geology at the University of South Florida. Her work has focused on computational methods in geologic hazard assessment and geophysical research, which have highlighted new methods for optimization of volcanic hazard models, uncertainty assessment for volcanic hazard models, and applications in real-time monitoring of geophysical processes. She has authored numerous codes, including the probabilistic volcanic hazard assessment codes currently in use by the US Nuclear Regulatory Commission and the Nuclear Waste Organization of Japan. She is co-editor of Statistics in Volcanology (with H. M. Mader, S. G. Coles and C. B. Connor, 2006).
