I am interested in linking the biogeochemical effects of multiple human stressors with the structure and function of aquatic communities. Some aspects of aquatic systems that I study in the lab and field are:

  • Species, population and community level adaptations to dynamical changes in water geochemistry due to altered UV radiation, metal complexation, and varied flow regimes resulting from climate change.
  • Food web and detrital dynamics mediated by essential trace metals, fungal processing, and aquatic biogeochemistry across watersheds.
