His research investigates how jurors make decisions and the effect of being in a group on individuals’ attitudes and behaviours. He is one of the leading jury decision-making researchers in Australia, using both simulations and surveys of actual jurors to understand the factors that influence jurors' decisions. He is currently working on three Australian Research Council funded projects on jury decision making. The first is looking at how stereotypes about sexual assault influence jurors' decisions, the second examines the way in which expert testimony is perceived and utilised by jurors, and the third is looking at the influence of the court room design on how jurors think about the defendant in criminal trials. He runs the Applied Social Psychology Lab in the School of Psychology.
