Biographical Sketch

I am an eco-geochemist: an aqueous geochemist interested in the coupled dynamics of ecology and geochemistry in freshwater systems. I earned my PhD from 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. Following my PhD I worked as 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 am currently a Senior Scientist and Head of the Biogeochemistry Section at the The Academy of Natural Sciences of Drexel University and an Assistant Research Professor in Drexel’s Dept. of Biodiversity, Earth and Environmental Sciences. Here, my research has expanded to include the effects of conservation activities on catchment water quality and ecosystem health, and contaminant (esp. PFAS) dynamics in aquatic food webs.

Other Research

  • Point source nutrient effects on metabolic activity and reactive solute transport in an urban stream
  • Delaware River Watershed Initiative (science-driven conservation to improve water quality and ecosystem health).
  • Influence of channel morphology on stream metabolism, solute transport and nutrient cycling.
  • Organizing principles of hyporheic processing:
    • Hydrologic forcing & geologic setting controls on river corridor exchange & reach-scale ecosystem function.
    • Effects of woody debris and sediment histories on lowland stream ecosystem respiration.
    • Stream solute transport, timescales & metabolic activity under changing discharge conditions.
    • Impacts of water level on metabolism, transient storage & micro-thermal dynamics.
