Areas of Research: My lab studies visual processing, with a focus on issues of rapid cortical plasticity, population coding, and inter-areal communication. We use neurophysiological, computational and behavioral methods in our work.

Professional Interests

My lab investigates how visual information is encoded and processed by populations of cortical neurons, and how this processing is affected by recent stimulus history, or adaptation. Our work thus addresses issues of neural coding, cortical plasticity, corticocortical signaling, and the neuronal basis of visual perception. Our approach involves multielectrode recordings in early and midlevel visual areas of anesthetized and awake, behaving macaque monkeys. We use computational methods to interpret and understand physiological data, and psychophysical methods to relate our findings to human perception. We have also begun using optogenetic tools, to further our understanding of corticocortical signaling in primate cortex.
