I am a social psychologist with research interests in group judgment and decision-making, negotiations, and social influence. My primary line of research addresses psychological biases that prevent managers, consumers, and policy-makers from gaining maximum value from collaboration. I also study the conditions that make people willing to listen and be receptive to views and opinions they strongly oppose. My most recent work deals with structuring group interaction to maximize decision-making effectiveness.  

Prior to coming to the Kennedy School, I served as a Lecturer at the Wharton School, University of Pennsylvania, where I taught Negotiations at both the MBA and the undergraduate levels. I received a PhD in Social Psychology from Stanford University and a BA in Psychology from Harvard University.
