Research Synopsis:

I am interested in human vision, machine vision, and computational modeling of visual processing. My primary research is concerned with how the visual system estimates object properties from the information available in the light signal incident at the eye. To study this general problem, I conduct psychophysical experiments to investigate questions such as how object color appearance is related to object surface properties under a wide range of illumination conditions and how color is used to identify objects. In addition, I am interested in developing machine visual systems that can mimic human performance and in understanding the neural mechanisms of vision.
