I use epidemiological techniques to elucidate causes of adult mental illness with an emphasis on cohort studies and psychotic disorders. I also research service configurations to identify and treat those with mental illness early and effectively, and use RCT methods at service and individual levels. Population prediction of psychosis and early intervention in psychosis are clinical interests. Take a look at http://www.psymaptic.org for work with James Kirkbride and the CLAHRC, and http://www.cameo.nhs.uk for the EIS I set-up with Kim Masson, Ed Bullmore and others.
