Expertise

Bird Migration • Climate Change • Urbanization • Biogeography • Macroecology • Environmental Pollution

My research program addresses a broad range of questions in avian ecology, behavior, evolution, biogeography, and conservation. Recent lines of inquiry include migration ecology, urban ecology, environmental pollution, temperature extremes, and island biogeography. I address these questions primarily using eBird and radar data in combination with a diversity of other ecological and environmental data sources. The central objective of my current research program is to explore the broad-scale patterns and drivers of seasonal bird distributions, with a special focus on the implications of global environmental change for migratory bird populations.
