Previously, he was Assistant Professor, then Associate Professor of Organisational Behaviour at INSEAD. He was co-director of the INSEAD Social Sciences Research Centre from 2007-2010. He received his PhD in Organizational Behavior from the Stanford Graduate School of Business, Stanford University.Marwan's research focuses on negotiations, emotions, and group decisions. He is interested in understanding how the emotional and behavioral strategies that negotiators can elect to adopt influence their effectiveness and efficiency. In that, he has focused on what might be termed “the dark side” of negotiations. For example, he has investigated how and when issuing a threat, expressing anger and other emotions, expressing emotional inconsistency, being suspicious, or making the first offer may influence the process and outcome of negotiations. He also is interested in understanding how the interplay of emotions and information influences decision-making in groups, both social and task groups. For example, he has investigated how negative emotions affect behavior in social aggregates, or why the expression of certain emotions stimulates thinking in small groups.Marwan's research has been published or is in press in the Journal of Applied Psychology, the Journal of Experimental Social Psychology, Personality and Social Psychology Bulletin, Psychological Science, and Group Decision and Negotiation.
