Our research is focused on active sensory acquisition. We seek to understand neural mechanisms and computational principles that animals use to actively acquire sensory information in complex, dynamic environments. We are interested in systems-level integration and interactions of:

We study these processes in the electrosensory system of weakly electric fish, using a combination of behavioral, electrophysiological, and computational neuroscience approaches.
