Associate Professor of Biology, Director of Environmental StudiesTaylor Science Center 2037
Andrea Townsend's research is focused on understanding how land-use changes affect the behavior, health and populations of wild birds. In recent work, Townsend examined how urbanization promotes transmission of West Nile virus and food-borne pathogens in crows. She used satellite telemetry to examine how they might transport these diseases along migratory pathways. Townsend and her students address these questions using a combination of field observations, experiments and laboratory techniques. They work with both free-living and captive birds. She earned her doctorate in ecology at Cornell University and her A.B. in biology from Bowdoin College. Townsend conducted post-doctoral research at the Cornell Lab of Ornithology and the Smithsonian Institution. She was a faculty member at the University of California, Davis, prior to joining the faculty at Hamilton.
