We conduct research at the interface of aquatic ecology, limnology, evolution, animal behavior, and ecotoxicology. We ask general, conceptual questions and we do so with a wide diversity of aquatic organisms including algae, aquatic plants, zooplankton, snails, bivalves, insects, crustaceans, amphibians, and fish.

Since 2014, our research has included much more work on lake ecosystems as part of The Jefferson Project at Lake George. This is an unprecedented effort to combine a Smart Sensor Network, advanced computer models (weather, runoff, lake circulation, and food web models), and leading-edge experimentation. Our goal is to serve as a global blueprint for how scientists and engineers can study and understand human impacts on the environment and, in turn, inform decision makers about how to mitigate these human impacts.

Below is an overview of our research.

PESTICIDE ECOTOXICOLOGY

​

• Ecological effects

  • Effects on behavior, morphology, and survival

  • Impacts on species interactions and food webs

  • Effects of pesticide mixtures

  • Cross-tolerance among insecticides

  • Synergistic effects with predator stress

  • Synergistic effects with competitor stress

  • Lag effects of pesticide exposure

  • Mitigating insecticides with aquatic plants

​

• Evolutionary effects

  • Evolved tolerance across landscapes

  • Evolved populations alter food webs

  • Inducible pesticide tolerance by sublethal exposures

  • Inducible pesticide tolerance by predator cues

  • Phylogenetic patterns of pesticide tolerance
