Education

Doctor of Philosophy, University of Wisconsin-Madison. Limnology and Marine Science (2012)

Master’s of Science, Michigan State University. Fisheries and Wildlife (2006)

Bachelor of Science, University of Wisconsin-Madison. Biology (2003)

Areas of Interest

Climate change, long-term trends in fish populations, aquatic invasive species, food webs/community dynamics, landscape models of fish habitat, and adaptive management.

Research

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.
