Bert van Roermund has been professor of legal philosophy at Tilburg University since 1989. After his Rousseau research, he published widely on various fundamental legal concepts and contemporary legal problems (constitutional review, democracy, European integration). His monograph on Law, Narrative and Reality (1997; also in Spanish) concluded a period of research in law and language. Since 1997 he focuses on problems of authority and representation (sovereignty, identity, normativity, reconciliation) in supra-national contexts like the European Union and the World Trade Organisation. He is currently in charge of the research programme Legislation and Identity, Strategies of Authoritative Representation (2004-2009).
