I am a Professor in the School of Psychology. My research aims to better understand the development of expertise, processes of evidence evaluation in criminal trials, and to improve the communication between experts and lay decision-makers in forensic settings.

Research Goals
To understand lay interpretations of complex statistical and probabilistic evidence presented in criminal trials
To examine the development of expertise
To develop models for evaluating expert evidence
To improve the quality of forensic science expert evaluative opinions
To facilitate clear communication between experts and lay decision-makers

Research in Detail
My collaborators and I use online crowd sourcing platforms and electronic questionnaires to examine the decision-making processes of large international samples of lay decision-makers.We use crime scenarios based on actual case facts, and expert evidence derived from real forensic technologies, to assess the impact of evidence and evidence presentation characteristics on belief-updating. We collaborate with legal practitioners and academics, law enforcement operatives and organisations, psychologists, statisticians and forensic scientists in order to ensure the validity of our experimental approach and maximise the practical implications of our work.
