About my research

I want to understand the neural mechanisms that transform sensory information into visual perception. My primary research goal is to study how information from our two eyes is used by the brain to construct a 3-dimensional world. Using stereoscopic vision, we can judge accurately the position and size of objects in external space. Our ability to see in depth arises in the cerebral cortex, where the similarity and differences in retinal images are compared and fused to create a single image. While early research suggested that stereopsis arises in the primary visual cortex, we now know that many regions in the visual hierarchy respond to binocular disparity. One critical objective is to understand to which extent different regions participate in stereopsis and binocular visuo-motor tasks.

My main methods are to apply concurrent functional MRI and psychophysics to study the contribution of cortical regions to visual perception. I work with participants with normal vision and volunteers with amblyopia, a condition that causes abnormal stereopsis.

I supervise MSc students and final year undergraduate students for their research projects and give tutorials in psychology and biomedical sciences.

Human Brain Activation

Activation to stimuli defined in binocular depth. This image shows a pattern of BOLD-activity (hot spots) displayed on the computationally inflated right hemisphere of an example participant. Visual areas and oculo-motor areas are tagged in bold black letters.
