Diversity & group decision-making

Diversity is a key value in democratic societies both for reasons of equity, inclusion and legitimacy and because of its ramifications for the performance of groups such as juries, design teams, and scientific communities. I have worked to characterize diversity’s varied meanings, develop appropriate measures for quantifying them, examine pathways by which diversity can impact group performance, and specify different dimensions of this impact. My current research here focuses on homophily‘s impacts on the communication structure and dynamics of diverse groups, and issues of justice and fairness in collective inquiry.
