Hydrologist

Short Biography

 

I received my Bachelor of Science degree in Biology in 1980, my Master of Science degree in 1986 and my PhD in 2000 in Environmental Biology from George Mason University. I am a hydrologist in the National Research Program (NRP) of the U.S. Geological Survey (USGS) Water Resources Division in Reston, Virginia. I have been with the NRP since 1979 and am currently a member of the Vegetation and Hydrogeomorphic Relations Project where I lead the submersed aquatic vegetation (SAV) task. I have designed and conducted studies directed toward the recognition and understanding of processes that affect estuarine, riverine, lacustrine and palustrine ecosystems. This included fundamental research on the factors affecting diversity and the distribution of aquatic vegetation in estuaries and the effects of vegetation on water quality and flow. I have studied factors influencing distribution and abundance of submersed aquatic macrophytes in the Chesapeake Bay, and worked with the Environmental Protection Agency and other members of the Chesapeake Bay Program to set water-quality goals and habitat restoration targets for submersed aquatic vegetation in the Chesapeake Bay. In addition, I participated in USGS multidisciplinary studies in the south Florida Everglades focusing on determining vegetative resistance to flow to improve surface water models and in the Chesapeake Bay watershed focusing on understanding the source and fate of nutrient accumulation in floodplain sediments.
