I am an Assistant Professor in the Department of Neuroscience and Zuckerman Institute at Columbia UniversityI study the neural basis of primate vision – how neurons represent the visual world and how they mediate perception and action. This tremendous feat of biology is implemented by a collection of interconnected areas of the cerebral cortex and a variety of neuronal types. This neural circuit, its nodes and its codes, are the focus of my research. I am particularly interested in how neurons at higher stages of cortical processing acquire a preference for visual shape information. To investigate these processes in new ways, I am currently developing genetic techniques for the functional dissection of primate neural circuits.
