Allard R. Feddes is an assistant professor at the Social Psychology department of the University of Amsterdam. Allard studied Social Psychology and Organizational Psychology at the University of Groningen, the Netherlands (1998-2004). In this period he participated in the ERASMUS exchange programme and studied at the National University of Maynooth, Ireland (Sociology and Philosophy). For his MA thesis studies he spent six months at the Psychology Department of Simon Fraser University in Vancouver, Canada. Allard did his PhD in Social Psychology at the International Graduate College "Conflict and Cooperation between Social Groups" at the Friedrich-Schiller-University Jena (Germany, 2004-2007) where he studied associations between intergroup contact and development of prejudice in ethnic majority and minority children. In the period 2007-2011 he worked as a post-doctoral researcher at the Social Psychology department of ISCTE-IUL (Lisbon University Institute) in Lisbon, Portugal. Among other topics he studied development of prejudice, stereotyping, and perceptions of social status in Portuguese children of different ethnic background. Since 2011 he has studied processes of (de-)radicalisation at the University of Amsterdam and the University of Milano-Bicocca (Italy). He is involved in the AmsterdamPinkPanel (a research panel of currently 1200+ members from the Netherlands) doing research on LGBT-related topics such as perceptions of safety, psychological well-being, and hate-crime.
