I am an Assistant Professor of Information Technology and Organizations in the H. John Heinz III College of Public Policy, Information Systems, and Management at Carnegie Mellon University. I also have a partial appointment in the Human-Computer Interaction Institute in the School of Computer Science. I study Computer-Supported Cooperative Work, particularly the design and use of communication technologies. I am interested in understanding and addressing problems of attention, interruption, multi-tasking, and overload in the modern workplace. In my current research I am examining how distributed groups coordinate their work, and what technological and social interventions can facilitate coordination. My goal is to design interfaces and organizational processes that more efficiently manage human attention at work.
