Research Focus:

Stereopsis is a binocular cue to depth that on its own can provide extremely accurate depth information and a compelling sense of the third dimension (3D). It is thought to be important in such everyday tasks as walking up stairs, or threading a needle. This cue to depth is based on differences in the position of the images of an object on the two retinae, known as binocular disparity. The aim of my basic research program is to understand how the human visual system processes this binocular disparity signal to obtain depth information. My lab has identified distinct cortical systems that process fine and coarse disparities; we have shown that the coarse disparity system is used to provide depth information when images cannot be fused. In other studies we have shown that coarse stereopsis does not require fusional eye movements, and that this system is used by children with amblyopia to make accurate depth judgements. In addition to this fundamental research, my laboratory is actively involved in applied research projects with industry partners. We have been involved in collaborative work with companies such as Christie Digital, and IMAX to evaluate factors that influence our perception of depth and motion in 2D and 3D display content.
