My research integrates the study of ecology, behavior and evolution into the fields of biogeography, community ecology and invasion biology by using modeling and experimental techniques to link patterns of species occurrence with processes that determine species persistence, coexistence, and movement across spatial scales. My most recent research has focused on 1) The transition in life history traits of species between natural and urban environments 2) How urbanization and biological invasions effect geographic patterns of diversity and 3) How climate and habitat restoration influence community structure. See my research topic sections for more in-depth details.
