Profile

Iím interested in visual perception, in particular face perception and motion perception. Iíve also recently developed an interest in applying psychophysical methods to areas of research in which such techniques have not widely been used. In terms of motion perception Iíve spent much of my career looking at the hierarchical organisation of motion processing mechanism Ė in other words, what types of mechanisms do we need to account for our perception of motion over a wide variety of stimuli. Much of my current motion work tries to tease apart the contributions and interactions involved in the processing of local and global motion. In face perception Iíve been looking at face adaptation, specifically using face adaptation to investigate the nature of our underlying representation of facial identity and facial expression.
