I am an interdisciplinary freshwater scientist interested in the coupled interactions between geochemistry, hydrology and ecology in stream and groundwater systems. My goal is to both advance basic scientific understanding and provide tools and concepts to aid in the sustainable use, management and restoration of water resources & aquatic ecosystems.
Prior to starting at Oak Ridge National Laboratory I was Head of the Biogeochemistry Section at The Academy of Natural Sciences of Drexel University in Philadelphia, PA, and a staff scientist at the Helmholtz Center for Environmental Research – UFZ in Leipzig, Germany. I completed my Ph.D. in Geology at the University of Florida. There, I was a fellow in the NSF IGERT ‘Adaptive Management: Wise use of Water, Wetlands & Watersheds’, which trained scientists to collaborate in interdisciplinary teams to address the complex issues of coupled human and natural systems and the interface of science and policy required to manage them. I received my B.S. in Geology from The College of William & Mary.
