Dr Matthew Hollocks

Clinical Psychologist

Area of expertise
  • Autism spectrum disorders
  • Emotional and behavioural problems in neurodevelopmental conditions
  • Psychological treatment of anxiety and depression

Dr Hollocks is a Clinical Psychologist in the Neuropsychiatry and Challenging Behaviour Team and a Visiting Lecturer in the Department for Child and Adolescent Psychiatry, King’s College London.

Dr Hollocks undertook research training at the Department of Child and Adolescent Psychiatry, King’s College London, completing a PhD investigating co-occurring anxiety in children with autism. This was followed by a period of post-doctoral research at the Department of Clinical Neurosciences, University of Cambridge. Here he conducted research investigating the brain changes associated with depression and apathy in neurological diseases. He then completed his training in clinical psychology, including a specialist placement at the Cambridge Centre for Paediatric Neuropsychological Rehabilitation.

Dr Hollocks is actively involved in research aiming to understand why autistic young people have high rates of mental health difficulties, and how best to develop and improve psychological interventions for those with neurodevelopmental conditions.
