Notes on Contributors

Barry Barnes was educated in the Natural Sciences and in Sociology before taking a post in the Science Studies Unit, in the Faculty of Science at Edinburgh University, eventually becoming Director of the Unit and Professor of Sociology. He is now co-director of the ESRC Centre for Genomics in Society at Exeter. His work focuses on the sociological study of knowledge generation and evaluation in science, and on the basis of the credibility of scientific expertise. In 1998, he accepted the Bernal Prize for his career achievement in that field. He has also published extensively on the fundamental problems of the social sciences, particularly on collective action problems, status groups as generators of [exclusionary] collective action, and self-referring knowledge as constitutive of social order and systems of power.
