Marc Smith

Marc Smith is a sociologist specializing in the social organization of online communities and computer mediated interaction. Smith leads the Connected Action consulting group and lives and works in Silicon Valley, California.  Smith co-founded and directs the Social Media Research Foundation, a non-profit devoted to open tools, data and scholarship related to social media research.

Smith is the co-editor with Peter Kollock of Communities in Cyberspace (Routledge), a collection of essays exploring the ways identity; interaction and social order develop in online groups. Along with Derek Hansen and Ben Shneiderman, he is the co-author and editor of Analyzing Social Media Networks with NodeXL: Insights from a connected world, which is a guide to mapping connections created through computer-mediated interactions.

Smith’s research focuses on computer-mediated collective action: the ways group dynamics change when they take place in and through social cyberspaces. Many “groups” in cyberspace produce public goods and organize themselves in the form of a commons. Smith’s goal is to visualize these social cyberspaces, mapping and measuring their structure, dynamics and life cycles. While at Microsoft Research, he founded the Community Technologies Group and led the development of the “Netscan” web application and data mining engine that allowed researchers studying Usenet newsgroups and related repositories of threaded conversations to get reports on the rates of posting, posters, crossposting, thread length and frequency distributions of activity.  He contributes to the NodeXL project that adds social network analysis features to the familiar Excel spreadsheet.  NodeXL enables social network analysis of email, Twitter, Flickr, WWW, Facebook and other network data sets.

Smith received a B.S. in international area studies from Drexel University, an M.Phil. in social theory from Cambridge University, and a Ph.D. in sociology from UCLA. He is an adjunct lecturer at the College of Information Studies at the University of Maryland. Smith is also a Distinguished Visiting Scholar at the Media-X Program at Stanford University.
