Although organizations often hope to achieve positive outcomes by having people work together, problems with trust and motivation are two reasons for why individuals in groups do not reach their potential. Despite these challenges, interdependent work need not have negative outcomes. A unifying theme of my work is to better understand how the social context (e.g., group composition) can be structured to help facilitate positive outcomes when people work with one another. Specifically, my research generally examines how factors in the social setting influence: 1) task motivation and performance, and 2) how trust is formed, and repaired if broken.
