0485 - photo on websiteDr Vaughan Bell is a Principal Clinical Psychologist with the Psychological Interventions Clinic for Outpatients with Psychosis (PICuP) where he sees clients for psychological treatment, supervises and trains professionals working with people with psychosis and jointly coordinates research and development for the service. Clinically, Vaughan works with people who experience psychosis in all its forms and, in addition, he has a special interest in working with people who have psychosis alongside cognitive difficulties (problems with memory, concentration or problem-solving) or conditions such as epilepsy or brain injury


Vaughan completed a PhD at Cardiff University on the cognitive neuropsychiatry of psychosis before completing his clinical training and Doctorate in Clinical Psychology (DClinPsy) at the Institute of Psychiatry, King’s College London, in 2008 where he specialised in both psychosis and neuropsychology.

Since qualifying Vaughan has worked in both mental health and neuropsychology services in the UK and abroad. He worked in Colombia for several years in inpatient, community and emergency mental health before returning to the UK where he has worked in neurorehabilitation, neurodevelopmental, and mental health services.

Vaughan also has an interest in public engagement and works to communicate the latest research about mental health and to reduce stigma through improving public understanding.

Dr Vaughan Bell is a Chartered Psychologist with the British Psychological Society and a registered Clinical Psychologist with the Health and Care Professions Council. He is also a full member of the Colegio Colombiano de Psicólogos and a fluent Spanish speaker.


Vaughan is a Visiting Researcher at the Institute of Psychiatry, Psychology and Neuroscience, King’s College London, and a Senior Clinical Lecturer at the Division of Psychiatry, University College London, where his research focuses on understanding the psychology and neuroscience of psychosis, unusual experiences and neuropsychological difficulties. This involves both working to understand these conditions as well as developing ways of assessing and evaluating the problems associated with them.
