I am an eco-geochemist: an aqueous geochemist by training with an interest in the interactions between ecology, geochemistry and hydrology in freshwater systems. As a research scientist, my goal is both to advance basic understanding and to provide tools and concepts to aid in the sustainable use, management and restoration of water resources and aquatic ecosystems.

I am currently a research scientist and section Leader for Biogeochemistry at the Academy of Natural Sciences of Drexel University's Patrick Center for Environmental Resealch and an assistant research professor in Drexel University's Department of Biodiversity, Earth and Environmental Sciences.  Prior to this I was a staff scientist at the Helmholtz Centre for Environmental Research - UFZ, Dept. of Hydrogeology where my research focused on the impact of the hyporheic zone on whole-stream solute and ecosystem dynamics. I completed my PhD in 2013 at the University of Florida, investigating the hydrologic and 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 and Watersheds', which incorporated interdisciplinary coursework and research experiences to train scientists to address emerging issues in coupled human and natural systems and the interplay of policy and science required to manage them. Prior to my PhD I received my BS from The College of William & Mary.
