Research in my lab takes an integrative, comparative, and multi-disciplinary approach that draws on questions and methods from behavioral ecology, evolutionary biology, comparative psychology, human psychoacoustics, and neurophysiology to provide answers to fundamental questions about animal communication, such as: (i) How do animals encode information about themselves in the production of acoustic signals? (ii) How do animals acquire information about other conspecifics through the perception of acoustic signals? (iii) How do these processes function in natural habitats and noisy social environments? And (iv) how do these processes evolve? While open to work on numerous taxa, our principal study organisms are frogs, in which acoustic communication mediates many important behaviors related to reproduction.
We are currently focused on two major questions. First, how do animals perceive the vocalizations of other individuals in noisy social environments? In this context, we are investigating questions related to “auditory scene analysis” and the so-called “cocktail party problem” to understand how the frog auditory system forms auditory objects of acoustic signals and segregates the signals of one male from the din of background noise in a large breeding chorus. Second, what is the role of acoustic signaling in mediating the aggressive male-male interactions that arise from sexual selection and take place in social environments that are both temporally and spatially variable? In this context, our work investigates vocally mediated social recognition, behavioral plasticity, learning, and honest signaling in male frogs that defend calling sites or breeding territories.
