Larry Winter , NCAR Deputy Director

Larry Winter is the Deputy Director of the National Center for Atmospheric Research (NCAR). In that role he assists with scientific leadership, provides administrative oversight, and helps formulate strategic goals, budgets, and programmatic priorities for the institution. Dr. Winter is also an Adjunct Professor in the Department of Hydrology and Water Resources at the University of Arizona. Before moving to NCAR, Dr. Winter was leader of three groups at Los Alamos National Laboratory. During 1997-1999 he led the Computer Research and Applications Group; from 1995-1997 he led the Geoanalysis Group; from 1990-1995 he led the Applied Mathematics and Statistics Team.

Dr. Winter received a M.S. in Geoscience in 1976, a M.S. in Applied Mathematics in 1980, and a Ph.D. in Applied Mathematics in 1982 from the University of Arizona. His research interests include the stochastic theory of subsurface flow and transport and the applications of parallel and distributed computing in scientific research. He has authored or co-authored over 40 refereed journal articles and book chapters since receiving his Ph.D. and has organized numerous workshops and conference sessions. He has been an invited speaker at many national and international conferences, workshops and major universities.

Dr. Winter has balanced his active research interests with unusually strong community service and leadership. He was the Governor of New Mexico's Science Advisor from 1999 to 2002. He has served on numerous boards and panels, including the National Ecological Observatory Network (NEON) Advisory Board; the Executive Committee, and later the Advisory Board, of the NSF Science and Technology Center for Sustainable semi-Arid Hydrology and Riparian Areas (SAHRA); the New Mexico Experimental Program to Stimulate Competitive Research (EPSCoR) Committee; and the Executive Committee of the Center for Non-Linear Studies at Los Alamos.

Among his honors are a Science Applications International Corp. (SAIC) Publication Prize in Mathematics, Computer Science, and Operations Research and a Los Alamos Distinguished Performance Award. Larry’s outside interests include writing and the history of the American West, and he has won a Best Story of the Year award from Arizona Highways magazine.
