Major in research methods of the social sciences (mathematical sociology), and minors in sociological theory and economics, at the Catholic University of Nijmegen (now Radboud University). During my study I lectured in statistics and introductory research methods. I took also part of the research advisory group of the faculty. After the finalisation of my doctoral study I started working as an assistant professor in research methods at the department (later faculty) of Public Administration at the University of Twente. In 1992 I defended my dissertation there. (De maatschappelijke betekenis van beroepsprestige; The societal impact of occupational prestige). My supervisors were Prof. dr. G.P.A. Braam (University of Twente) and Prof. dr. J. Berting (Erasmus University).
