FW 4107 - Principles of Fisheries Science and Management
Climate change, long-term trends in fish populations, aquatic invasive species, food webs/community dynamics, landscape models of fish habitat, and adaptive management.
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.
