Research Interests:
How do species come to occur where they do in space and time? What features on the landscape allow a species to persist in that landscape? How do human influences over large scales affect a region's "ecological health?" Can we apply what we know to inform land use decisions and work toward restoration? These are the broad questions that guide most of my research; I try to answer them primarily through field studies of breeding songbirds. You can learn more about specific projects on my lab webpage.
