Research Interests

Our research employs neurophysiological and computational approaches to study the primate visual system. Specifically, we are interested in the dynamics of visual processing at the level of individual neurons and populations. We study how the temporal structure of neuronal responses can teach us about cortical circuits, how form processing is accomplished by a distributed network of neurons, and how populations of neurons integrate information provided by inputs within and between cortical regions.
