Andrew Flanagin received his M.A. and Ph.D. in Communication Theory and Research from the Annenberg School for Communication, at the University of Southern California. Prior to this, he earned a B.A. in Sociology and American Studies from Yale University and worked for several years as a Management Systems Consultant, Systems Analyst, Computer Programmer, and a Foreign Liaison and Technology Transfer Specialist. These experiences reflect his overarching interest in the use of technologies in contemporary society.

Professor Flanagin's research broadly considers processes of social influence in digitally-mediated environments. His research focuses on the use of social media for information sharing and assessment; people's perceptions of the credibility of information gathered and presented online; processes of collective organizing as influenced by the use of contemporary technologies; and organizational technologies, including the affordances they offer and the dynamics they promote.

Related to this research program, Professor Flanagin teaches courses on the Internet and Web, social media, research methods, collaborative technologies, communication theory, technologies and organizations, and organizational theory and new forms of organizing.

Professor Flanagin is former Director of the Center for Information Technology & Society at UCSB (, which is dedicated to research and education about the cultural transitions and social innovations associated with technology.
