Short Biography

 

 

B.S. in Geology in 1988 from Rensselaer Polytechnic Institute, Troy, NY. M.S in Hydrogeology in 1992 from Syracuse University, Syracuse, NY. Work at U.S. Geological Survey, Georgia Water Science Center, Atlanta, GA from 1992 to present as a Hydrologist and a Research Hydrologist. Worked on various water-quality and hydrologic studies.

Current responsibilities include being project chief of Panola Mountain Research Watershed (PMRW), a Water, Energy and Biogeochemical Budgets (WEBB) Program watershed. The WEBB programs goal is to understand processes controlling water, energy and biogeochemical budgets over a range of spatial and temporal scales, including the effects of atmospheric and climatic variables; and is part of the USGS’s Climate and Land Use Change Program. Also responsible for method design, estimation, and reporting of streamwater constituent fluxes and trends for the USGS’s National Stream Quality Accounting Network (NASQAN), which monitors the water quality of U.S.’s large rivers.

Research Interests & Actvities

Research at Panola Mountain Research Watershed (PMRW), a Water, Energy and Biogeochemcial Budgets (WEBB) Program watershed, includes investigating processes that control the movement and solute composition of water along hydrologic pathways that produce streamflow; determining the relative contributions from a variety of sources of solutes observed in streamwater, including atmospheric deposition, cation exchange, and primary mineral weathering; investigating biogeochemical processes controlling the regulation of soil-solution chemistry and element cycling, and; determining and predicting the effects of climate change on these processes. Research activities for USGS's National Stream Quality Accounting Network (NASQAN) program include optimizing sample design and streamwater constituent flux estimation implementation for improving constituent fluxes. Through both the PMRW project and the NASQAN program, I have worked on improving the prediction of empirical water-quality regression models, developed new methodology for estimating streamwater constituent fluxes, and developed a technique for identifying trends in streamwater constituent concentrations and fluxes.
