Hi! I’m an associate professor in the Communication Studies and the Electrical Engineering and Computer Science (by courtesy) Departments at Northwestern University, where I also direct the Social Media Lab and lead the new undergraduate Digital Media Module. I am affiliated with the Media, Technology and Society and the Technology and Social Behavior graduate programs.

My research interests and teaching center on how people coordinate, collaborate and interact online, with a particular focus on attention. I’m interested better understanding and supporting how people in pay attention to their friends and colleagues online, and how they explain when they are unavailable to do so. My work has been generously supported by the National Science Foundation, Google Inc., and the Natural Sciences and Engineering Research Council of Canada; and published at the ACM CHI and CSCW conferences and in various journals related to Human-Computer Interaction and Communication.12
