David R. Millen

Director of a User Interface Design Group responsible for the user interface design of advanced business communications systems and exploratory prototype development of advanced speech applications and pen-based interfaces, Millen has also served as a senior researcher at IBM Center for Social Software, T.J. Watson Research Center in Cambridge, Massachusetts.

There he designed and built new social software services, and explored the social, business, and technological implications of these new tools through large-scale field studies of use. Important projects included the Dogear Social Bookmarking System, the Beehive Social Networking Service, and the Cattail Social File Sharing System, which were all pioneering examples of social software designed for enterprise settings.

As part of this research program, he completed empirical studies of incentive and reward systems in social applications, and examined novel approaches to social recommenders and social search. He also investigated how social applications accelerated awareness of cultural differences and how novel systems could be designed to better support intercultural collaboration.

Millen holds a BA from Columbia University, an MS in Management from Purdue University, and a PhD in Cognitive Psychology from Rutgers University. Prior to joining IBM, he worked at AT&T Research and Bell Laboratories, where he explored how new technologies changed employee work activities, organizational roles, and patterns of communication.

Millen has served as an adjunct faculty member at Rutgers University and at Tufts University, where he taught a class on The Social Web.
