I study how rapid environmental change impacts population and community dynamics in northern ecosystems. My current projects include testing how rapid warming in Greenland impacts Arctic mosquitoes and their role as pests of caribou, and modeling how climate change impacts the availability of thermally-suitable habitat for brook trout in New Hampshire. I enjoy using a combination of observations, experiments, and models to tackle ecological questions relevant to coupled human-natural systems. Please see my publications for an idea of the various projects I have completed.
