My research focuses on the community ecology of communication: the way that interactions within and between species affect the production and perception of signals. To address these questions, I study a variety of taxa including crickets, katydids, frogs, bats and birds. My current research focuses on modeling phenological patterns in bird activity and understanding why birds sing when they do. To quantify singing activity, I am using automated recording and machine learning approaches to find and identify bird calls from a network of recorders in Sapsucker Woods and in Hubbard Brook Experimental Forest in New Hampshire.

Previously, I have held post-doctoral positions at Dartmouth College (Neukom Fellowship), the University of Wisconsin and the Smithsonian Institute for Tropical Research. I completed my PhD at Dartmouth College and a B.S. in Biology at Denison University.
