Konstantine Georgakakos is the Managing Director of the Hydrologic Research Center in San Diego, California. He is also an Adjunct Professor with the Scripps Institution of Oceanography of the University of California, San Diego, and with the Department of Civil and Environmental Engineering of the University of Iowa, Iowa City. His research activities have included interfacing ensemble and probabilistic forecasting with decision models for multiobjective reservoir management and agriculture in Northern California. He has also developed measures of utility of uncertain surface meteorological forecasts for hydrologic and water resources applications by propagating uncertainty in coupled systems and in downscaling, and producing probabilistic diagnostic indices for utilizing climate and weather ensemble model forecasts. He has led the development of operational forecast and management systems in Northern California, at the Panama Canal, over the Nile River basin, in Korea, and in Central America as part of the technology transfer programs of the Hydrologic Research Center. Dr. Georgakakos holds a degree in civil engineering from the National Technical University of Athens, and master’s and doctoral degrees in civil engineering from the Massachusetts Institute of Technology.
James Hansen is an assistant professor in the Department of Earth, Atmospheric, and Planetary Sciences at the Massachusetts Institute of Technology.

Upmanu Lall is Professor and Chair of Earth and Environmental Engineering at Columbia University. His principal areas of expertise are statistical and numerical modeling of hydrologic and climatic systems and water resource systems planning and management. He has over 25 years of experience as a hydrologist. He has been the principal investigator on a number of research projects funded by the U.S. Geological Survey, the National Science Foundation (NSF), the U.S. Air Force, the National Oceanic and Atmospheric Administration (NOAA), U.S. Bureau of Reclamation, Department of Energy, and Utah and Florida state agencies. These projects have covered water quantity and quality and energy resource management, flood analysis, groundwater modeling and subsurface characterization, climate modeling and the development of statistical and mathematical modeling methods. He has been involved as a consultant with specialization in groundwater flow and contaminant transport modeling covering mining operations, streamflow modeling and water balance, risk and environmental impact assessment, site hydrologic evaluation and as a reviewer and as an expert on a number of other hydrologic problems. He has also taught over 20 distinct university courses.
Clifford F. Mass is a professor in the Department of Atmospheric Sciences at the University of Washington. He received his B.S. in 1974 in physics at Cornell and his Ph.D. in atmospheric sciences at the University of Washington in 1978. He has been a faculty member at the University of Washington since 1981. His research interests include synoptic and mesoscale forecasting techniques, regional weather phenomena, and mesoscale modeling using the Penn State-NCAR MM5 modeling system. He works with ensemble prediction, including maintaining a real-time mesoscale ensemble system and involvement with the Multidisciplinary University Research Initiative on predictability, and has collaborated for many years with the National Weather Service (NWS) on regional forecasting problems. He currently leads a research group that has studied a wide variety of topics, including heavy precipitation and flooding, wind and snow storms, numerical forecasting strategies, as well as weather phenomena unique to western North America. Dr. Mass also leads the real-time MM5 forecasting effort at the University of Washington.
