My main areas of interest are forensic and clinical psychology, including the factors underpinning offending behaviour and to the prevention of suicide and self-harm. I have a special interest in psychopathy and how the behavioural and psychological features of the psychopathic disorder lead to offending behaviour. I have published widely on the science of risk assessment and safety planning in mental health services.

My background is as a Consultant in Clinical and Forensic Psychology and I have spent my career as a clinical-academic working in secure mental health facilities, attempting to address the needs of people with severe mental illness or personality disorder who can present a danger to themselves or to the general public. I have a strong interest in clinical and forensic psychology as it applies to the family and criminal courts and have acted as an expert witness in many legal cases.

  • PS-M29 Psychopathy and Sexual Offending

    Psychopathy is a severe personality disorder strongly associated with violence and antisocial behaviour and places a large demand on both mental health services, and the judiciary system. The module will cover the measurement of psychopathy, the aetiology of psychopathic traits, and models of psychopathic behaviour from a biosocial viewpoint. Sexual offending is a major societal problem. The module will examine how deviant sexual interests may occur, and how these might be measured. The issues of the assessment of risk posed by sexual offenders and the management/treatment of offenders will be discussed.

  • PSY319 Final Year Independent Research Project

    Students conduct an independent research project under the supervision of a member of staff. The research topic is decided in conjunction with supervisors and Research topics. Students must obtain ethical approval, design, conduct, analyse and write up a piece of research in order to achieve Graduate Basis for Chartership with the British Psychological Society (BPS).

  • PSY321 Forensic Psychology

    The module will first explore the role a psychologist in forensic matters as they pertain to criminal behaviour, with a strong emphasis on violence and sexual violence. This will include how information is gathered and used in order to understand offending behavior and its use in risk management and treatment. The module will then go on to consider the role of mental disorders in relation to issues such as criminal responsibility and the treatment of such disorders, before turning to examine in detail the relationship between one particular form of mental illness (psychosis) and one particular form of criminal behavior (serious violence to others). The module will then consider how we go about the examination of individuals in terms of risk of violence to others and sexual violence and conclude by focusing on the management of offenders, including how psychology has informed forensic risk assessment procedures as well as making a substantial contribution to offender rehabilitation.
