Professional Experience

GIS Programmer/Analyst, Tetra Tech EC, Bothell, WA, 2009 to present

  • Provide GIS support for multiple USDA Forest Service regional initiatives, including Climate Change Vulnerability Assessments for Regions 1 and 6, a Multiple Threat and Values Assessment for the Western Wildland Environmental Threat Assessment Center (WWETAC), and the calculation of Fire Regime Condition Class (FRCC) for Washington and Oregon.
  • Assist in re-design and development of GIS portion of Ecological Information Clearinghouse website (; preparation of raster GIS datasets and maps of potential vegetation, plant association groups and FRCC for public download, including preparation of FGDC-compliant metadata.
  • Develop models and scripts in ArcMap (Python, VBA, Model Builder) for a variety of GIS tasks including derivation of forested stand year of origin from fire history and related layers; converting symbol sets between Arc/Info and ArcGIS; pre-processing of data layers for input into Fire Regime Condition Class models.

GIS Programmer/Analyst, USDA Forest Service, Everett, WA, 2004 to 2009

  • Designed and developed numerous raster GIS models (e.g., cold air drainage, topographic roughness, evapotranspiration) and tools in support of ArcInfo-based application for prediction of vegetation zones and plant association groups across the Pacific Northwest.
  • Developed and maintained GIS layers used in the modeling process, including weather station-based precipitation and temperature, fire history and forested stand year of origin, NED DEM, NLCD landcover, NRCS soils, ecology plot measurement data, and geology and regolith data.
  • Developed a wide variety of map atlases in ArcMap 9.x of vegetation zones, plant associations, geology and regolith, soils, fire history and stand year of origin, and color orthophototography.
  • Developed high-quality maps and graphics for presentations and for publication.
  • Researched scientific literature in support of model development and enhancement, in areas including geomorphometry (land surface analysis), cold air drainage, potential evapotranspiration and soil and geology effects on potential vegetation types.

Cadastral Project Manager, Washington Department of Fish and Wildlife, Olympia, WA, 2001-2004

  • Analyzed business needs of agency for information on the agency's owned and controlled lands; worked closely with end users to assess data needs, and develop use cases to test database design.
  • Designed data model in Visio for geodatabase of Agency owned and controlled lands for ArcGIS and MS SQL Server.
  • Designed and implemented pilot mapping project on two of the agency's Wildlife Areas.

GIS/Technical Services Manager, Washington Department of Fish and Wildlife, Olympia, WA, 1994-2001

  • Supervised up to five GIS analysts, cartographers, applications developers and technical support staff in a wide range of GIS and applications development projects.
  • Provided end-user support for over 100 staff in areas of hardware and software support, including support for ArcInfo, ArcView, Powerbuilder applications, and Microsoft Office.
  • Researched, recommended and purchased GIS software and hardware, including ArcInfo, ArcView and assorted software, plotters, digitizers, PC's and UNIX workstations.
  • Planned and implemented agency's migration of GIS systems from UNIX-based Arc/Info to Windows-based ArcGIS.

GIS Programmer/Analyst, Washington Department of Fish and Wildlife, Olympia, WA, 1992-1994

  • Wrote extensive menu system for field personnel to access GIS data layers, including ability to query, filter and view the data, and to compose and print maps and reports.
  • Performed complex analyses on a wide variety of GIS data types, including analysis of TM-derived land cover data using ArcInfo Grid; analyses of riparian data on stream networks using dynamic segmentation; habitat analyses for a variety of wildlife species.
  • Lead GIS Analyst for multi-agency, multi-year Integrated Landscape Management project.

GIS Technician, New Hampshire Department of Environmental Services, Concord, NH, 1990-1992

  • Developed AML-based menu interface for staff to design and produce town-based maps of threats to groundwater quality.
  • Designed and produced digital maps for a wide variety of purposes, from report-size to poster maps for legislative hearings.
  • Field located threats to groundwater quality, using GPS technology.

Research Scientist, Complex Systems Research Center, UNH, Durham, NH, 1985-1989

  • Wrote new and modified existing mathematical models in FORTRAN depicting the oceans' circulation and role in the global carbon cycle.
  • Wrote technical reports and research summaries for funding agencies, and research articles for the scientific literature.
