I am a researcher and clinical neuropsychologist, interested in different aspects of normal and pathological brain function using behavioural and brain imaging techniques (EEG and fMRI) in healthy and brain-damaged (and especially epileptic) patients. I am particularly involved in higher-level visual and spatial function. Our present research interests focus at present on how brain processing changes with respect to stimulus relevance.
