Justine Cassell (Ph.D., University of Chicago) is Associate Vice-Provost of Technology Strategy and Impact at Carnegie Mellon University , and until recently was Director of the Human-Computer Interaction Institute in the School of Computer Science. Cassell comes to CMU from Northwestern, where she was the founding director of the Center for Technology and Social Behavior joint PhD in Communication and Computer Science, and of the Center for Technology and Social Behavior. Before Northwestern, Cassell was a tenured faculty member at the MIT Media Lab, where she headed the Gesture and Narrative Language research group. Cassell's research focuses on understanding natural forms of communication, and then creating technological tools for those forms of communication and linguistic expression to flourish in the digital world. In particular, she is credited with developing the Embodied Conversational Agent, a virtual human capable of interacting with humans using both language and nonverbal behavior. More recently Cassell has investigated the role that the ECA can play in children's lives, as a part of a Story Listening System, an interactive support for learning language and literacy skills.

David Gerritsen
David Gerritsen degerrits at andrew dot cmu dot edu

David is interested in improving human-computer interaction by studying the ways humans behave with each other. He believes that the most effective and humane tools are designed with a deep understanding of everyday human behavior.
Currently his research involves observing 12 year olds taking turns tutoring each other in simple algebra over several weeks. These students are teaching him about how young people build, sustain, or fail to sustain rapport over time. Such rapport behaviors will then be modeled and implemented into virtual agents, changing the nature of educational software by adding dimensions of social interaction between the human user and computational agent.
David was a psychology major at the University of Utah with research centered on cognitive processing and social norms found in human-computer interaction.  He is most fascinated by how humans reason about the perceived intentionality of virtual agents. This background informs his current research by providing a foundation in cognitive models and a theoretical framework for the psychological world of virtual agents.
