Biography

I am a hydrologist for the U.S. Geological Survey Arkansas Water Science Center and hold a Bachelor of Science and a Master of Science in Geology from the University of Arkansas at Little Rock. Since joining the USGS in 2001, I have been involved in collecting water levels and creating potentiometric surfaces for several aquifers within the State; characterizing the local recharge area of a spring that is habitat to the endangered Hell Creek Cave crayfish; developing the hydrogeologic framework for the Mississippi embayment aquifer system for use in the Mississippi Embayment Regional Aquifer Study (MERAS) groundwater flow model; developing a Hydrologic Simulation Program--FORTRAN (HSPF) model of Little Rock's drinking water supply watershed; developing a HSPF model of Conway's drinking water supply watershed; developing a PRMS model of the entire Landscape Conservation Cooperative Gulf Coastal Plains and Ozarks area simulating daily streamflow; developing dynamic parameters for land use and land cover data extending back to 1938 to aid in the development of the National Hydrologic Model; and developing a PRMS model, loosely coupled to a MODFLOW model, to determine the extent of the recharge area of the hot springs of the Hot Springs National Park. I also currently run the geophysical logging program within the center using our own geophysical logging truck and geophysical tools.
