Biography

My PhD research involved liaison with legal professionals, police officers and social workers. Five empirical studies investigated numerous issues regarding the detection of deception including nonverbal cues to deceit, the analysis and application of Criteria-Based Content Analysis and the perceptions of people with regard to cues to deceit. I took a two-year PostDoc Research Associate post at the University of Wales, Swansea working on a Leverhulme Trust funded project entitled, 'The influence of sleep loss, personality and confidence on eyewitness suggestibility'. In 1997 I joined the Department of Psychology at Portsmouth as a member of academic staff. I am currently the Interim Head of the Department of Psychology and a Reader in Psychology and Law.
