Research

My laboratory studies animal communication. We are interested in how communicative signals are produced, travel through the environment, how they are detected, how the receiver responds to them, and ultimately how they have evolved. The colorful tiger moths on which we concentrate provide a diversity of interaction and allow a comparative approach to many evolutionary questions. My students and I combine high-speed infrared videography, 3D-video reconstruction of behavior, classic behavioral observation, analytical chemical methods, electrophysiological techniques, and cladistic analyses to explore communication systems that are often beyond our own sensory capabilities.

We are currently studying the following topics:

Bat-tiger moth arms race: When a tiger moth hears the echolocation sounds of an insectivorous bat they answer with a series of ultrasonic clicks. These ant-bat clicks serve several functions depending on the context. They can warn bats of a distasteful prey, deceive bats into thinking the prey is toxic, and even jam bat sonar. The more we learn the more surprises we find.

Reproductive Isolation in Darwin’s tiger moths in the Galápagos: Like Darwin’s finches tiger moths in the genus Utetheisa have undergone rapid radiation in the Galapágos archipelago. We are studying the roles of female and male pheromones in reproductive isolation in this group. The answers may hold secrets about how many species have come into existence.

Behavioral genetics of autism in fruit flies: The causes of autism are largely unknown. However genetic mutations are likely part of the equation. Mutant fruit flies are helping us understand the basis of this increasingly common disorder.
