I am Professor of Epidemiology and Therapeutics and Deputy Head of Department, Department of Psychosis Studies, and Academic Director of the Psychosis Clinical Academic Group. I apply the techniques of epidemiology and population research to study the causes, consequences and treatments of psychoses, particularly in treatment resistant schizophrenia and personalised medicine. I lead STRATA, an MRC-funded multi-centre consortium developing stratified medicine for schizophrenia, and CLEAR, an RCT of clozapine in early psychosis.
I remain an active clinician and spend 50% of my time working in the NHS as Honorary Consultant Psychiatrist at the National Psychosis Unit, at the Bethlem Royal Hospital, South London and Maudsley NHS Foundation Trust. This is the only national tertiary referral centre for treatment-resistant psychosis in the UK. I am also Director of Maudsley Debates and a trustee of SANE.
