Jean Tillie’s research focuses on multicultural democracy, and more specifically on radicalisation and extremism, anti-immigrant sentiment and the European electorate’s preference for extreme right-wing parties, and the political integration of migrants. He is the coordinator of the EURISLAM international comparative research project to analyse the social and cultural integration of Muslims, and in the past has coordinated international studies on voter turnout and voting behaviour among migrant populations during municipal elections.

Tillie recently co-authored a book with Joop van Holsteyn, Henk van der Kolk and Kees Aartsby about Dutch voters and politics from 1998 to the present (Rumoer. Nederlandse kiezers en politiek na 1998, Amsterdam University Press). His previous publications include a book on Salafi Jihadis in Amsterdam, co-authored with Marieke Slootman, Amin Majdy and Frank Buijs (Salafi-jihadi’s in Amsterdam. Portretten, Aksant, 2009), and another on multiculturalism in the Netherlands (Gedeeld land. Het multiculturele ongemak van Nederland, Meulenhoff, 2008).

Tillie has worked at the UvA since 1995, as an associate professor of Political Science since 2004 and from 2007 also as professor by special appointment of Electoral Politics, with a special focus on the relationship between electoral processes and their economic, cultural, ethnic and social contexts. From 2012 until 2014, he was the head of the UvA’s Political Science Department. Tillie has also been programme leader of the Challenges to Democratic Representation research group at the Amsterdam Institute for Social Science Research (AISSR) and deputy director of the Institute for Migration and Ethnic Studies (IMES).
