Areas of Interest

My research focuses on pattern and process in aquatic communities and ecosystems. I employ statistical analyses of historical data, observational field studies, simulation modeling, and large-scale experimentation to answer applied science questions in a real world context.

Areas of interest include:
-Climate change
-Long-term trends in fish populations
-Aquatic invasive species
-Food webs/community dynamics
-Landscape models of fish habitat
-Adaptive management
