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 (GMU). I am an affiliate professor in the Environmental Science and Policy Department at GMU. I am a steering committee member for the National Capital Region Partnership for Regional Invasive Species Management (NCR-PRISM). From 1979 to 2017 I was a hydrologist in the National Research Program (NRP) of the U.S. Geological Survey (USGS) Water Resources Division in Reston, Virginia, and a member of the Vegetation and Hydrogeomorphic Relations Project where I lead the submersed aquatic vegetation (SAV) project. I am an aquatic plant ecologist and have designed and conducted studies directed toward the recognition and understanding of processes that affect aquatic 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 estuaries and worked with members of the Chesapeake Bay Program to set water-quality goals and habitat restoration targets for submersed aquatic vegetation in the Chesapeake Bay. I also participated in USGS multidisciplinary studies in the south Florida Everglades focusing on determining vegetative resistance to flow to improve surface water models. In addition, I quantified the uptake of nutrients in plant material relative to other nutrient cycling processes to better define the important role of vegetation in nutrient and sediment trapping in a Piedmont floodplain. Prior to retiring in 2017, I revealed a cryptic introduction of an invasive nonnative aquatic plant, Water Chestnut (Trapa bispinosa), in the northeastern United States. I found that this new type of Water Chestnut is in the early stages of spread in the Potomac River watershed (VA and MD) and Roanoke River watershed. I continue efforts to inform managers that if it goes unchecked, we could face an epic control challenge that would both undo past decades of successful Water Chestnut eradication efforts and undermine more recent water quality improvements that have resulted in restoration of an increasingly diverse and abundant population of SAV.
