Generation and evaluation of Bayesian Networks, Evaluation of Psychologically Informed Planned Environments, Artificial Intelligence, Adult antisocial syndrome


Since his initial appointment to Queen Mary in 2009, he has worked on studies including the epidemiology of violence; outcomes research in forensic mental health services; causal inference networks for violence risk management; clinical sub-types of personality disorder and psychopathy; substance misuse as a risk factor for violence; and patterns of service use by young men in the UK. His current research is into causal mechanisms in risk assessment using Bayesian Networks, and the effectiveness of psychosocial interventions for offenders with personality disorder. In 2015 he received funding from the Ministry of Justice to conduct a mixed-method evaluation of the combined Ministry of Justice/NHS England initiative to develop Psychologically Informed Planned Environments (PIPEs) within HM Prison Service and the Probation service across England and Wales.
