Research Interests

My PhD research topic was "The role of motion streaks in human motion perception". I am interested in how the brain combines orientation and motion cues to resolve directional ambiguities in motion. I am also interested in multisensory integration and time perception, particularly in how this relates to musical ability and experience. Other interests include visual awareness and binocular rivalry.
