I am an Assistant Professor of Information and Decision Sciences in the Carlson School of Management at the University of Minnesota. I hold a Ph.D. in Organization Science from Carnegie Mellon University, a M.E. in Systems Engineering and a B.E. in Electronic Engineering from Xi'an Jiaotong University in China.

My research centers around two significant trends that began in the middle of the 20^th century yet continue to transform businesses and interpersonal lives in our society: the increasing reliance upon groups to get work done and the use of information technologies to support group interactions and collaboration. Residing at the intersection of the two, my research examines how we can design and manage information technologies to support effective group interactions and collaboration. Specific topics include online community design, business applications of web 2.0, knowledge management, distributed collaboration, and computational modeling of social and organizational systems. My work has been published in or forthcoming at Management Science, MIS Quarterly, Organization Science, Journal of MIS, Journal of Management Studies, Organization Studies, The Academy of Management Annals, and the Proceedings of AOM, CHI, CSCW, HICSS, ICIS, and WikiSys.

My research on online volunteer groups is supported by National Science Foundation. My research on crowdsourcing is supported by the Carlson School Small Dean Grant. I serve on the editorial board of Organization Science. I also serve as ad hoc reviewers for MIS Quarterly, Information Systems Research, Management Science, Journal of MIS, Journal of AIS, and several other journals. I received the Information Systems Research Best Reviewer Award in 2009.
