My PhD dissertation takes a multilevel approach to investigate the effects of anthropogenic noise on tree swallows. Specifically, I experimentally test the behavioral, physiological and molecular, and population-level responses to traffic noise. I believe this integrative research is important in order to get a better understanding of full scale of effects caused by increased noise exposure. Further, as traffic noise is pervasive in the U.S., with 83% of the U.S. is approximately half a mile from a road,  research on noise effects is likely necessary to better inform conservation efforts.
