Gwen Wittenbaum

My research examines communication and social influence in small group and interpersonal contexts. Past research has examined information exchange in decision-making groups, tacit coordination in group performance, and perceptions of group member competence. More recently, I have studied social ostracism in task groups and communication in "exerbuddy" relationships. I serve as Director of Master’s Studies in Michigan State University’s Communication Department and also as an Associate Editor of Social Influence.
