Barry Wellman, FRSC (born 1942) directs NetLab as the S.D. Clark Professor of Sociology at the University of Toronto. His areas of research are community sociology, the Internet, human-computer interaction and social structure, as manifested in social networks in communities and organizations. His overarching interest is in the paradigm shift from group-centered relations to networked individualism. He has written more than 300 articles, chapters, reports and books. Many have been co-authored, with students comprising about half of his nearly 100 co-authors. Among the concepts Wellman has published are: "the network city" (with Paul Craven), "the community question", "computer networks as social networks", "connected lives" and the "immanent Internet" (both with Bernie Hogan), "media-multiplexity" (with Caroline Haythornthwaite), "networked individualism" and "networked society", "personal community" and "personal network" and three with Anabel Quan-Haase: "hyperconnectivity", "local virtuality" and "virtual locality".
