Rob Stewart is Professor of Psychiatric Epidemiology and Clinical Informatics, and leads Clinical and Population Informatics in the Maudsley NIHR Biomedical Research Centre. He has been Academic Lead for the Maudsley’s Clinical Record Interactive Search (CRIS) platform since its development in 2007-8. CRIS is an internationally unique data resource comprising de-identified full electronic mental health records from the South London and Maudsley NHS Foundation Trust (over 400,000 patients) with extensive enhancement through multiple data linkages and natural language processing (‘text-mining’) algorithms. CRIS has been used extensively for research to improve the understanding of mental health conditions and mental healthcare services, and has supported over 150 peer-reviewed publications.  

Rob Stewart joined the Institute of Psychiatry as a junior researcher in 1996 and has worked on the epidemiology of dementia and other late-life mental disorders and on a range of International Mental Health initiatives, as well as his more recent activity in Clinical Informatics. He is a practising Consultant in Liaison Old Age Psychiatry and an NIHR Senior Investigator.  

Research Interests
