Evolution, Behavior, and Conservation Biology

My research asks why animals do the things they do, and how we can do a better job of mitigating our impacts on the natural world. Combining lab work with fieldwork on remote islands, I explore how evolution and human activity shape the genetics and behavior of animals, sometimes conveniently intersecting with my love of trail running and mountain adventures.. Recurring research themes include mate choice, parental investment strategies, population structure, and host-parasite evolution. Most of this work is with seabirds and songbirds.  I use a mix of lab methods (mainly genetics tools) and field methods.

My recent teaching at Bates includes: Avian Biology,  Genetics of Conservation Biology (BIES 333), Evolution and Interactions of Life (BIO 206), a Host-Parasite Evolution version of BIO 195, Biological Research Experience: Molecules to Ecosystems (BIO 204), and Advanced Topics in Evolution (BIO 355).
