Peter's current research is concerned with delineating the mental and neuronal processes that underlie the symptoms of mental disorder. In particular, he employs the techniques of cognitive psychology, functional Magnetic Resonance Imaging (fMRI); Event Related Potential (ERP), oscillatory activity in the Electro encephalogram (EEG) and Magneto encephalography (MEG) recording to investigate attention, executive function and motivation in healthy individuals and the impairment of these processes in mental disorders, especially in schizophrenia and ADHD. Throughout his clinical career his major clinical interest has been in the management of psychotic illnesses and he currently works in the Nottingham Psychosis Early Intervention Service. His major research interest has been investigation of the pathophysiological mechanisms of the symptoms of schizophrenia using the techniques of cognitive psychology and neuroimaging.
