My research is directed at understanding visual perception in humans and in animals. Much of my research concentrates on figure-ground perception in natural images, particularly using texture, colour or motion. These visual cues are of fundamental importance for visuomotor behaviour (navigation, reaching), detecting objects (i.e., breaking camouflage), depth perception (motion parallax, shape from motion or texture gradients), and the sensation of self-motion. Anomalies of motion, texture and colour perception are of clinical interest in ocular pathology, aging, and brain damage.
