My research is in the field of sensory ecology, which investigates how sensory systems evolve to encode the environmental cues that are crucial for an animal’s survival and reproduction. I am fascinated by how sensory system evolution interacts with the behavior and ecology of animals. Most of my work explores the acoustic world of bats and their insect prey. This type of research requires an interdisciplinary approach combining physiological, behavioral, ecological, and phylogenetic data, obtained both in the lab and in the field.
