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".

. It showed, for example, that sisters provide siblings with much emotional support, while parents provide financial aid. The support comes more from the characteristics of the ties than from the networks in which they are embedded. This research also demonstrated that wives maintain social networks for their husbands as well as for themselves.

Although Wellman's work has shifted primarily to studies of the Internet (see section below), he has continued collaborative analyses of the first and second East York studies, showing that reciprocity (like social support) is much more of a tie phenomenon than a social network phenomenon and that the frequency and supportiveness of interpersonal contact before the Internet was non-linearly associated with residential (and workplace) distance

Social network theory

Concomitant with his empirical work, Wellman has contributed to the theory of social network analysis. The most comprehensive statement is in his introductory article to Social Structures, co-edited with the late S.D. Berkowitz. This work reviews the history of social network thought, and suggests a number of basic principles of social network analysis.

More recent and more focused theoretical work has discussed the "glocalization" of contemporary communities (simultaneously "global" and "local") and the rise of "networked individualism" – the transformation from group-based networks to individualized networks. American Sociological Association

Social network methods

Wellman's methodological contributions have been for the analysis of ego-centered or "personal" networks – defined from the standpoint of an individual (usually a person). As batches of personal networks are often studied, this calls for somewhat different techniques than the more common social network

 practice of analyzing a single large network.

A 2007 paper, co-authored by Wellman (with Bernie Hogan and Juan-Antonio Carrasco), has discussed alternatives in gathering personal network data. A paper with Kenneth Frank showed how to tackle the problem of simultaneously analyzing personal network data on the two distinct levels of ties and networks. "Neighboring in Netville" has been cited as the only published study of personal networks from a known roster of potential network members. The most widely cited papers are the simplest: co-authored guides to analyzing personal network data while using the statistical software packages SAS

Internet, technology and society

Wellman has often worked in collaboration with computer scientists, communication scientists and information scientists.
In 1990, he became involved in studying how ordinary people use the Internet and other communication technologies to communicate and exchange information at work, at home and in the community. Thus his work has expanded his interest in non-local communities and social networks to encompass the Internet, mobile phones and other information and communication technologies.

Work networks and ICTs

Wellman's initial project ("Cavecat" which morphed into "Telepresence

 and computer supported collaborative work (CSCW).
Caroline Haythornthwaite (for her dissertation and other works) and Wellman analyzed why computer scientists connect with each other – online and offline. They discovered that friendships as well as collaborative work were prime movers of connectivity at work.

Wellman and Anabel Quan-Haase also studied whether such computer-supported work teams were supporting networked organizations, in which bureaucratic structure and physical proximity did not matter. Their research in one high-tech American organization – heavily dependent on instant messaging

 was only partially fulfilled in practice. The organizational constraints of departmental organization (including power) and physical proximity continued to play important roles. There were strong norms in the organization for when different communication media were used, with face-to-face contact intertwined with online contact.

Community networks and ICTs

As a community sociologist, Wellman began arguing that too much analysis of life online was happening in isolation from other aspects of everyday life. He published several papers (alone and with associates) arguing the need to contextualize Internet research, and proposing that online relations – like off-line – would be best studied as ramified social networks rather than as bounded groups. This argument culminated in a 2002 book, The Internet in Everyday Life (co-edited with Caroline Haythornthwaite), providing exemplification from studies in a number of social milieus.

Wellman did empirical work in this area: he was part of a team (led by James Witte) that surveyed visitors to the National Geographic Society

The large U.S. national random-sample survey analyzed in the Pew Internet report, "The Strength of Internet Ties" (with Jeffrey Boase, John B. Horrigan and Lee Rainie) also showed a positive association between communication online and communication by telephone and face-to-face. The study showed that email is well-suited for maintaining regular contact with large networks, and especially with relationships that are only somewhat strong. The study also found that Internet users get more help than non-users from friends and relatives.

 has become more recursively multi-step as the result of the Internet's facilitation of information seeking and communication. Recent research (with Tracy Kennedy) has argued that many households, like communities, have changed from local groups to become spatially-dispersed networks connected by frequent ICT and mobile phone communication. Other NetLab researchers, besides those noted in the text and the notes, include Julie Amoroso, Dean Behrens, Vincent Chua, Jessica Collins, Dimitrina Dimitrova, Zack Hayat, Julia Madej, Maria Majerski, Mo Guang Ying, Diana Mok and Bárbara Barbosa Neves.

Teaching and mentoring

Wellman mentors graduate and undergraduate students in courses about community, social network analysis, and technology and society. He has co-authored with 51 students, including five undergraduates and one high school student. In 1998, he received the annual "Mentoring Award" from the International Network for Personal Relationships.
