Research Interests

We seek to understand how the brain encodes behaviorally relevant information. To drive the full range of neural computations performed by the brain, we test the limits of perception and learning in insects using naturalistic stimuli. We explore olfactory behavior in insects that have evolved to solve specific tasks, such as olfactory learning and navigation in honey bees, and we use Drosophila to test the causal relationship between neuronal activity and behavior by exploiting the genetic tools for manipulating and monitoring activity in identified neurons. The methods we use are comprised of behavioral analysis, functional imaging and electrophysiology.
