I grew up (intellectually) in the tradition of social psychology, and much of my work has focused on prejudice and political behaviour as individual and social phenomena. My PhD research focused on a longitudinal study of voting behaviour in the 1996 election - the first under a proportional representation electoral system. More recently I've moved into studying adolescent mental health, and particularly the vexed questions of why some people hurt themselves deliberately with, and without, suicidal intent. This research has been supported by the Health Research Council and the Marsden Fund. Along the way I also teach and research about why people eat the things they do; people's beliefs in science, pseudoscience and conspiracies; psychopathy and narcissism; and a bunch of things that more 'credible' researchers wouldn't touch with a big stick.
