I am the Professor of Clinical Psychology and Rehabilitation at King’s College London. I was Director, NIHR Clinical Research Network: Mental Health and then Senior Spokesperson on Mental Health for NIHR CRN until 2017. I am now an NIHR Senior Investigator.

I edit the Journal of Mental Health and I'm Head of the School of Mental Health and Psychological Sciences at the Institute of Psychiatry, Psychology & Neuroscience. I have been involved in research on rehabilitation and recovery for people with severe mental illness for many years both in the development of services and the development and evaluation of innovative psychological treatments. My main current research themes concentrate on how to improve thinking difficulties so people can take advantage of opportunities for recovery and how to increase therapeutic activities in acute mental health services.

I founded and was the first director of the Service User Research Enterprise (SURE) which employs expert researchers who have experience of using mental health services.
