Research Interests

I am interested primarily in the evolution, ecology, and biogeography of birds. My current interests focus on the application of null models to multi-scale patterns of species diversity, the evolutionary consequences of hybridization, and the ecology and evolution of wood warblers. I am conducting long-term field studies in the Great Dismal Swamp and in the Appalachian Mountains of eastern North America.
