Research Description

A key question in cognitive science concerns how we acquire and interpret sensory information about our environment so that we can adaptively interact with objects and other individuals in that environment. Understanding the mechanisms that mediate our perceptual experiences is the first step in understanding more complex cognitive behavior. The long-term objective of my research program is to provide a better understanding of how the human visual system constructs neural representations based on sensory inputs, and how these neural representations shape various cognitive behaviors. Using psychophysics and fMRI, I am currently conducting studies investigating color representation at lateral geniculate nucleus (LGN), color representation during binocular rivalry, color-motion interaction.
