Dr. Christopher Swan is a community ecologist with general interests in how and why species assemblages are maintained in space and time. His research and outreach program takes a broad approach to understanding how biodiversity is organized in both natural and urban ecosystems. This is accomplished through interdisciplinary collaborations with scientific and community partners, as well as informal education. A major goal of his work is to understand how biodiversity is maintained through time in spatially constrained riverine ecosystems as well as in the urban environment in general. He studies aquatic invertebrate assemblages, plant communities and associated ecosystem processes. Dr. Swan is an active member of the Society for Freshwater Science and the Ecological Society of America. He teaches courses in ecology, field ecology, aquatic ecology, and quantitative methods both in the U.S. and abroad.
