Research Interests

The major theme of my research is the investigation of perceptual and sensory dynamics. This involves psychophysical investigation into how visual processes evolve over time as well as the perceptual mechanisms of visual and auditory temporal resolution. Other work is concerned with understanding the perceptual effects of context on various visual properties. This work includes examination of centre-surround interactions, visual crowding and contour integration and segmentation.
