He went on to complete medical training at Guys and St Thomas’ Hospitals before training in psychiatry on the MaudsleyHospital training scheme. He has a PhD in the cognitive neuroscience of autism and psychopathy. He is a member of the Royal College of Psychiatrists.

Research and Teaching

Dr Deeley researches cross-cultural psychiatry and social and cultural neuroscience, leading a research group at the Institute of Psychiatry in this area.  He also researches biological, psychological, and social influences on development, particularly in relation to common disorders such as autism, ADHD, conduct disorder, personality disorders, and psychosis. Dr Deeley’s educational role includes undergraduate and postgraduate medical teaching, as well as teaching on MSc courses at the Institute of Psychiatry including Mental Health in Learning Disability, Forensic Mental Health Research, and Mental Health Sciences. Dr Deeley contributes to a national training programme run by the Royal College of Psychiatrists to train psychiatrists in the diagnosis and support of adults with autistic spectrum disorders.
