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.
