I earned my B.A. in psychology from UCLA in 1985, and then my Ph.D. in psychology from UCSB in 1991. In 2010, I earned a Masters of Higher Education from the Australian National University.
I have been working at the ANU since 2003. Prior to that, I was at La Trobe University in Melbourne, Australia, and the University of Otago in New Zealand.
From 2007-2009 I was the President of the Society of Australasian Social Psychologists. In 2007, the Australian Learning & Teaching Council awarded me with a Citation for Outstanding Contributions to Student Learning.
Over the course of my academic career, I have conducted and published research on the social psychology of distributive, procedural, and restorative justice; leadership; social influence; helping; in-group favouritism and social identity management; linguistic masking; diversity; and social value orientations. In seeking to understand these diverse phenomena, I rely heavily on the theoretical and meta-theoretical assumptions of social identity and self-categorization theories.
