I am an eco-geochemist: an aqueous geochemist by training with an interest in the reciprocal interactions between ecology, geochemistry and hydrology in freshwater systems. As a research scientist, my goal is to both advance basic 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 Leader of the Biogeochemistry Section in the Patrick Center for Environmental Research 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 hydrologic & biogeochemical processes controlling 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. I received my BS in Geology from The College of William & Mary.
