Wesley Theological Seminary, Washington, D.C.BA Environmental Science (1987). University of Virginia, Charlottesville, Virginia,PRESENT ASSIGNMENT:DATES From: 2003 To: PresentDESCRIPTION: Research, development, and applications focuses on incorporating new simulation algorithms and enhancements of existing algorithms within the Precipitation-Runoff Modeling System (PRMS), the coupled Modular Groundwater Flow Model (MODFLOW) and PRMS simulation model\u2014GSFLOW, the coupled MODSIM-GSFLOW simulation code, and the National Hydrologic Modeling (NHM) Infrastructure. Development is driven by WMA research objectives of improving the understanding and simulation of watershed-scale hydrologic processes to climate and anthropogenic influences, environmental characteristics with input and requests from USGS and other Federal agencies, the academic community, and private sector scientists.RELEVANT EXPERIENCE:Research and development of the PRMS simulation model, most recently developing methods for input of historic and projected climate; dynamic parameters; and water-use information and enhancement of surface-depression storage and spatial and temporal characterization of model parameters for use in large model domains.Research and development of the coupled groundwater/surface-water simulation model (GSFLOW) and MODFLOW UZF and AG Package, and MODSIM-GSFLOW coupled simulation code.Research and development of a loosely-coupled, sub-daily simulation model using PRMS, NOAA-NWS Lag and K river routing model, and USACE HEC-ResSim Reservoir System Simulation model for a large watershed spanning portions of NY, NJ, and PA.Hydrologist, member of the Modeling of Watershed Systems (MoWS) project, USGS National Research Program, Central Region, Lakewood, Colorado (2003-2016)Senior Pastor, Greenwood United Methodist Church, Winchester, Virginia (1999-2002)Hydrologist, project chief and member of the Hydrologic Analysis Software Support Section, Reston, Virginia (1992-1996)Computer Scientist, project chief and site admistrator USGS National Research Program, Northeast Region, Office of Surface Water, Office of Groundwater, and Office of Water Quality, Reston, Virginia (1986-1992)Hydrologist, member of the Modeling of Hydrodynamic Systems project, USGS National Research Program, Northeast Region, Reston, Virginia (1981-1986)"
