I am a terrestrial ecologist with interests in the spatial dynamics of animal movements, populations, and biodiversity. My research spans a wide range of spatial scales from experimental to landscape studies. Habitats include conservation grasslands, forests, and agroecosystems. I emphasize the roles of landscape heterogeneity and land use on insect biodiversity, species interactions, and ecosystem services. In the laboratory, I use a wide range of quantitative tools including statistical modeling, spatial analysis, and geographic information systems.
