Eligible to supervise Masters and PhD - email supervisor to discuss availability.

I am a researcher and lecturer in the School of Psychology at the University of Adelaide. I work at the nexus of personality and social psychology with a specific focus on, and passion for, the moral psychology topics of justice, power, and forgiveness. Much of my research centres on how people’s perception of their just treatment drives their attitudes and behaviours in personal, relational, and political spheres. I also have an interest in psychometrics and latent variable structural equation modelling which I integrate into many of my research projects. Currently, I am working on improving self-report measures of the belief in a just world, a framework for validating manipulation checks, and developing a measure of the psychological experience of divine forgiveness.
