My work focuses on understanding the mechanisms that generate and maintain species diversity in a changing world. I specialize in the application of genomic tools to address basic and applied evolutionary and ecological questions, specifically related to migratory animals such as: 1) How are genetically distinct populations connected across the annual cycle? 2) What is the role of migration in generating species diversity? And 3) Which populations will have to adapt most to keep pace with climate change? The methods I use are integrative, combining field-based behavioral studies, population genetics/genomics, and GIS-based ecological modeling. My main focus is co-directing the Bird Genoscape Project, a large multi-institutional effort to harness genomic methods for migratory bird conservation.
