We are studying the evolution of social behavior and sensory systems by measuring the diversification of behavior and morphology across wild populations of zebrafish from India. For example, we are studying the relationships between behavior (aggression, boldness and learning) and the physical habitats in which zebrafish are found, as well as links between visual and chemical and tactile perception. We've also been collaborating with school teachers to bring these studies into the classroom. This work is supported, in part, by the National Science Foundation under Grant Nos.1257562 and 0543491.
