My work centres on understanding how capacity limited sensory systems integrate different sources of information to produce a coherent percept of the world. My areas of research include attention, visual cognition and memory, multimodal perception and translational interdisciplinary work. I use a variety of techniques in my research such as psychophysics, FMRI, EEG and eye tracking.
