Current Research Interest

Visual perception using psychophysics (present visual stimuli on the computer screen and record human response by button or key press). Perception of color and motion, the binding problem, visual search, attention.

Visual perception begins when the photons are absorbed by the photoreceptors in our retina. Numerous processes are involved between the creation of neural signals in the photoreceptors and conscious recognition of a meaningful object. For example, it seems so easy for us to follow the path of a basketball shown on TV screen. Its shape, color, and motion are integrated seamlessly even though the direction of motion may change abruptly or sometimes the part of the ball is occluded by the players. Our ability of such accurate perception is amazing when we consider that various visual features such as shape, color, texture, and motion are processed in the different parts of our brain. Along with the knowledge in physiology and neuroscience, we design psychophysical experiments that investigate how information is processed and integrated in our brain in order to reach perception of objects.
