Andrea B. Hollingshead is Professor of Communication in the Annenberg School of Communication, and has joint appointments with the Marshall School of Business and the Department of Psychology.

Professor Hollingshead is an expert on collective intelligence and group decision making. Her research identifies the factors, processes, and practices that make some groups more effective than others. She has studied a broad array of groups: from very small to very large; from face to face to those supported by technology across a wide range of contexts. Much of this work has been supported by the National Science Foundation.

She is the author of Groups Interacting with Technology (1994, with Joseph E. McGrath), Theories of Small Groups: Interdisciplinary Perspectives (2005, edited with Marshall Scott Poole), and Research Methods for Studying Groups and Teams: A Guide to Approaches, Tools and Technologies (2012, edited with Marshall Scott Poole.)  Her research has also appeared in top-tier journals in the fields of communication, management, and social psychology.

Some of Professor Hollingshead’s current projects include: a large descriptive study of online brand communities for the top 100 global brands; experiments investigating how people judge the credibility and expertise of contributors on Facebook and in other online communities; and field studies examining how collaborative crowdsourcing applications can be used to facilitate innovation and problem-solving in medical and other contexts.

Professor Hollingshead joined Annenberg in 2005 after serving on the faculty at the University of Illinois at Urbana-Champaign for 12 years, where she was an award winning teacher and researcher.  She holds a B.A. in Psychology from Yale University and an M.A. and Ph.D. in Social Psychology from the University of Illinois. Prior to graduate school, Professor Hollingshead worked in marketing research and advertising.

She teaches graduate-level courses on team communication and on integrated marketing communication at Annenberg. She also conducts workshops and short programs for professionals on those topics.

Professor Hollingshead is an avid scuba diver, and is the faculty advisor for the USC Scuba Club. She also enjoys cooking and running.
