Research areas

My research focuses on food web interactions involving fish in marine, estuarine and freshwater habitats. My recent research looks at fisheries policy tools and the conservation benefits they may provide. Of particular interest is the application of ecosystem approaches to fisheries management, as applied to fisheries targeting small forage fish, a species that play important roles in food webs.

I am looking for ways to measure the trade-offs between the vital ecosystem services small forage fish provide and their increasing commercial value. My lab conducts work in a wide range of marine ecosystems: from high seas pelagic systems to the inland seas of Puget Sound. We look at links between fishery governance (e.g., rights-based fishing) and ecological conditions, and attempt to understand the potential conflicts between fisheries as they target species that occupy distinct positions in food webs. Work in my lab tends to be quantitative, involving modeling and statistical analysis of complex data sets. We conduct fieldwork and collect data, particularly in Puget Sound, where we are working to understand the structure of the food web, how it varies in time and space and how it is impacted by climate change and other anthropogenic influences, such as hypoxia.
