STEFAN GRONDELAERS is a senior researcher and lecturer at the Centre for Language Studies of the Radboud University, Nijmegen, the Netherlands. With Dirk Speelman (University of Leuven), Grondelaers has confronted laboratory experiments and corpus analysis in multivariate studies of syntactic variation. After joining the research group Variation and Distance at the Radboud University in 2007, Grondelaers has focused on the attitudinal and ideological correlates of (especially syntactic) variation and change processes in Belgian and Netherlandic Dutch.
