Most people rely on vision for fundamental activities, such as navigating through the world and recognizing faces. Although the visual system of the brain has been a topic of great interest in scientific research, there are still many aspects of visual function that are poorly understood. Moreover, we lack technologies to restore these critical functions to those who suffer from vision loss.

During the next four years, my laboratory will pursue cutting-edge research on the visual cortex of the brain. We will develop a mathematical understanding of the computations carried out by neurons in brain areas responsible for recognizing faces and motion patterns, and we will determine how these areas interact with brain structures responsible for controlling eye movements. Our previous work suggests that this interaction may provide a probe into the mechanisms that go awry in mental disorders such as schizophrenia.

Finally, we will make use of this knowledge to develop new prosthetic devices that have the capability of restoring visual function in the absence of normal visual input. Together, these research projects will advance our understanding of one of the most important functions of the human brain and open new doors for the clinical treatment of vision loss.
