Research Interests: population ecology, spatial ecology, invasive species, networks, statistics, invertebrates, conservation, policy
My research goal is to understand the patterns and processes of species distributions so that we can develop effective conservation strategies. I like to focus on species that have direct impacts on humans, like invasive species and commercially-harvested species, and to integrate empirical data with statistical and mathematical models. I have worked in a variety of systems, including invasive marine fouling organisms in coastal Washington and on blue crab populations in the Gulf of Mexico. Now I am working on risk assessments for invasive amphibians, reptiles and aquatic crustaceans in the Great Lakes basin and exploring the links between invasive species introductions, the global shipping network, climate change and economics.
