   abstract: I am a research geologist with the U.S. Geological Survey, stationed
     in Lakewood, CO. I received my Ph.D. in geology from the Colorado School of
     Mines in Golden, CO in 1994 and have worked full-time as a geologist for the
     USGS in Denver since then.
   additionalType: staff profile page introductory statement

   abstract: My work involves creation of geologic maps and digital three-dimensional
     geologic models for framework geologic and hydrogeologic studies. I work in
     the western US, primarily in CA, NV, UT, and NM. In the past decade, I have
     been the lead within USGS Geologic Discipline with work on several major water
     resource-related projects in Nevada, Utah, and California, in collaboration
     with colleagues in the USGS Water Mission Area. I also conduct geologic mapping
     studies in California with USGS staff in Menlo Park; I have worked on the evolution
     of volcanic fields and sedimentary basins in response to the development through
     time of the San Andreas and related faults. I have also used subsurface geologic
     mapping to address groundwater-based issues in northern and central California.Current
     research projectsGeologic maps and 3D geologic framework models of the western
     US I am involved in multiple projects that are creating geologic maps and 3D
     geologic framework models in the western US, funded by the National Cooperative
     Geologic Mapping Program.Groundwater availability studies in California groundwater
     basins. I am creating digital 3D hydrogeologic framework models that portray
     the geometry and lithologic variability (a proxy for inferring hydraulic properties)
     of hydrostratigraphic units for input into numerical ground-water flow models.
     (work conducted with USGS CA WSC).National Geologic Synthesis. I am compiling
     data and developing methods for mapping subsurface geology at regional and National
     scales funded by the National Cooperative Geologic Mapping Program.
