I am a Professor in the Department of Communication Studies and the Department of Computer Science (by courtesy) at Northwestern University, where I direct the CollabLab: The Laboratory for Collaborative Technology.
My research is broadly in the fields of Human-Computer Interaction (HCI) and Computer-Supported Cooperative Work (CSCW) and Social Computing. I have an interest in developing a theoretical understanding of the role that visual information plays in supporting communication and group interactions. A key component of my work is the application of social and cognitive psychology theory to the design, deployment and evaluation of computing technologies.
I also hold a number of other positions at Northwestern University:
