Anja Eller is a social psychologist interested in intergroup relations, conflict, and contact, social identification and categorization, and comparative research across different cultures. Current research comprises longitudinal studies examining intergroup contact and its effects on cognitive, behavioural, and affective variables over time in the UK, Germany, Spain, and Mexico; intergenerational contact and attitudes; extended (indirect) contact and its capacity to reduce intergroup conflict; the role of different types of threat in intergroup relations; the role of meta-stereotypes in intergroup relations; and embarrassment.

Currently, she is funded by the Leverhulme Trust to investigate intra- and intergroup aspects of embarrassment. Jointly with Patrick Cronin (University of Abertay), Nick Hopkins (University of Dundee), and Steve Reicher (University of St Andrews), she also holds a grant from the Scottish Institute for Policing Research to examine collective disengagement and police-community encounters in Scotland.
