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.
I am a Senior Scientist and Head of the Biogeochemistry Section at The Academy of Natural Sciences of Drexel University and an Assistant Research Professor in Drexel's Department of Biodiversity, Earth and Environmental Sciences. Previously, I was a Staff Scientist at the Helmholtz Centre for Environmental Research - UFZ where my research focused on the impact of the hyporheic zone on whole-stream solute & ecosystem dynamics. I earned my PhD at the University of Florida investigating the varied controls on solute sources and cycling in streams, and the reciprocal interactions between solute availability and the elemental requirements of aquatic vegetation. During my PhD I was a Fellow in the NSF IGERT 'Adaptive Management: Wise use of Water, Wetlands & Watersheds', which trained scientists to address emerging issues in coupled human and natural systems and the interplay of policy and science required to manage them.
