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.
