He has completed several clinical trials in this area, and is working to evaluate innovative technologies for use as adjunctive interventions to help improve the accessibility of psychological interventions for people who have intellectual disabilities and autism.

Peter has been working on projects that aim to investigate psychological factors associated with criminal offending behaviour by people with intellectual and other developmental disabilities. These projects include developing improved psychological assessment tools for people with intellectual and developmental disabilities, developing and testing a virtual immersion training system for teaching social skills and perspective-taking with offenders with intellectual and developmental disabilities and undertaking a clinical trial of psychological therapies for people with intellectual disabilities who have a history of criminal offending. Peter has previously completed a set of funded projects that aimed to examine how moral development relates to criminal behaviour amongst men with intellectual disabilities.
He also has an interest in developing and evaluating 'talking' psychological therapies for people with intellectual and developmental disabilities. He was the Chief Investigator of the People with Asperger Syndrome and Anxiety (PAsSA) Treatment Trial which is a single-blind randomised control trial of group cognitive behavioural therapy for people with Asperger Syndrome and high functioning autism who also have problems with anxiety, funded by NIHR.
He has been awarded further grant from NIHR to investigate hospital care pathways for people with autistic spectrum conditions. See here for more information https://research.kent.ac.uk/match
