Peter completed his undergraduate degree in psychology at Memorial University of Newfoundland. He was awarded a Lord Rothermere Fellowship and qualified as a clinical psychologist in 2000 from the Institute of Psychiatry, King's College, London. He completed his PhD at the Tizard Centre, University of Kent as an NIHR Research Fellow. He then completed an NIHR funded postdoctoral fellowship.
He has worked within secure mental healthcare services for offenders with intellectual and developmental disabilities for twenty years. His research interests fall broadly within the area of developmental psychology and include the adaptation and evaluation of psychological therapies for people with intellectual and developmental disabilities. He is a non-medical approved clinician as defined with the Mental Health Act. He is registered as both a clinical and forensic psychologist, and is Honorary Associate Director of Research for Worcestershire Health and Care NHS Trust. He currently has a joint appointment together with Coventry and Warwickshire Partnership NHS Trust where he is responsible clinician working within forensic mental health services.
Peter has completed a variety of funded research projects involving people with intellectual and other developmental disabilities. These include a randomised control trial of group cognitive behavioural therapy for people with Asperger Syndrome and high functioning autism who also have problems with anxiety (PAsSA Trial), and more recently, and together with colleagues, an HTA funded randomised control trial of EMDR for people with intellectual disabilities (Trauma-AID), and an HTA funded randomised control trial of sertraline for the treatment of anxiety disorders in autistic adults (STRATA), as well as an NIHR funded study examining hospital care pathways for adults with autism detained in hospital (mATCH Study).
Peter is the co-convenor of RADiANT (ReseArch in DevelopmentAl NeuropsychiaTry) together with Dr Regi Alexander, Hertfordshire Partnership University NHS Foundation Trust. RADiANT is a consortium of NHS service providers which works in collaboration with academics in a number of universities. It seeks advice from service users, patients, families, charities, community leaders and a range of statutory bodies and organisations. RADiANT focuses on mental health and behavioural issues associated with five developmental conditions- Intellectual Disability (ID), Autistic Spectrum Disorders (ASD), Attention Deficit Hyperactivity Disorder (ADHD), Epilepsy (EPI) and Acquired Brain Injury (ABI). It is hosted by Hertfordshire Partnership University NHS Foundation Trust (HPFT).
