I am a social psychologist specialising in the study of collective behaviour. I completed my first degree at the University of Sussex, and my MSc and PhD at the University of Exeter. I have also studied and worked at the University of Amsterdam, the University of Abertay Dundee, and the Trust for the Study of Adolescence. I came back to Sussex in 1997.

I am a former editor of the British Journal of Social Psychology, and an associate editor of the European Journal of Social Psychology (from January 2027). I am a UCU rep for Psychology.
