My research is focused on how people share, evaluate and integrate diverse types of information, in professional environments such as digital libraries and interdisciplinary scientific collaborations, and in informal environments such as online social Q&A communities. By studying similar processes in diverse environments, I see my research as a bridge to help traditionally separate communities inform one another. Finding ways to provide access to multiple perspectives on common problems, and acknowledging diverse forms and sources of expertise, can yield more dynamic, well-grounded, and actionable information.
