We study the mechanisms and evolution of animal communication. In our approach, we integrate behavioral and physiological aspects of communication, and place this within an evolutionary perspective. By doing so, we hope to address one of the most interesting questions of all, How did the brain evolve?

Specifically, we address the following:

1. Sensory neurobiology of animal communication (Link): How do biases in sensory systems influence mate choice? How did those sensory biases evolve?

2. Sensory-endocrine interactions (Link):  How do social interactions regulate reproductive physiology? How do these physiological changes, in turn, influence behavior?

To address these questions, we use acoustic communication among frogs as a model system. We are currently working with the túngara frog (Physalaemus pustulosus) and its relatives. 

Technically, our research employs molecular cloning, in situ hybridization, quantitative PCR, immunocytochemistry, radioimmunoassay, and behavior analysis.
