Gillian Mezey is a Professor of Forensic Psychiatry. Her research is focused on psychological trauma as it affects victims of crime and violence, and on the impact of social exclusion and stigma in the recovery of individuals with severe mental illness.
Her early research was on the psychological effects of sexual and physical violence and abuse, and in particular on ways of improving the ability of health professionals to identify, intervene and respond effectively to such violence.
Her subsequent research was with individuals or groups who find themselves marginalised or excluded from society. These included victims of crime, female mentally disordered offenders, looked after children and young people and sexual offenders.
In recent years her research has focused on social exclusion and stigma in individuals with severe mental illness. Currently she is the principal investigator on a two year research project, funded by the National Institute for Health Research (NIHR) and the School for Social Care Research (SSCR). The research aims to validate a measure of social inclusion for use in mental health settings. This project is in collaboration with UCL and Bristol University.
Professor Mezey was appointed as a Consultant Forensic Psychiatrist and Senior Lecturer in Forensic Psychiatry at St George's, University of London and Springfield University Hospital in March 1991. Prior to this appointment, she trained in general and then forensic psychiatry at the Maudsley Hospital and the Institute of Psychiatry. She qualified from the Royal London Hospital in 1980.
She has published extensively in relation to psychological trauma, the effects of sexual and domestic abuse, and the effects of social exclusion and stigma on mentally disordered offenders. More recently she has conducted a major trial of peer mentoring in looked after children, as an intervention to reduce teenage pregnancy.
