Interests

With my advisor Peter U. Tse I work on mapping out the cognitive and neural bases of a number of aspects of visual perception and consciousness. My research so far has focused on the visual perception of form and motion, and how these two types of information interact with each other, as well as more higher level aspects of visual consciousness and representation. I am fascinated by the question of how the visual system disambiguate the inherently ambigious two-dimensional pattern of light that hits the retina, and how our rich meaningful and coherent three-dimensional perception of the visual scene come to be. I believe that the visual system must construct this scene, based on a number of assumptions. One of the goals of my research is to understand these assumptions, and to understand the neuronal circuits that could realize these constructive processes.
