Dr. Mark Klein (http://cci.mit.edu/klein/) is a Principal Research Scientist at the MIT Center for Collective Intelligence.  He received his PhD in Computer Science in Artificial Intelligence from the University of Illinois in 1989, and since then has worked for the Hitachi Advanced Research Laboratory, Boeing Research, Pennsylvania State University and (currently) the Massachusetts Institute of Technology, with visiting appointments at the Nagoya Institute of Technology and the University of Zurich.

His research draws from such fields as computer science, economics, operations research, and complexity science in order to develop and evaluate computer technologies that enable greater 'collective intelligence'  in large groups faced with complex decisions, especially those in the sustainability realm.

His current projects are looking at: large-scale on-line deliberation; negotiation protocols for problems with many interdependent issues; knowledge management that integrates virtual reality and social media; and managing coordination dysfunctions in large-scale networked systems. He has also made contributions in the areas of computer-supported conflict management for collaborative design, design rationale capture,  business process re-design, exception handling in workflow and multi-agent systems, and service discovery. He has over 200 publications in these areas, with over seven thousand citations and an h-index of 39.
