Justine Cassell

Justine Cassell (Ph.D., University of Chicago) is Associate Dean of the School of Computer Science for Technology Strategy and Impact at Carnegie Mellon University, Co-Director of the Simon Initiative, 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.

Timo Baumann

Timo Baumann is a Systems Scientist at the Language Technologies Institute at CMU. His research focuses on highly responsive dialog agents that engage in conversations beyond simple task-based interaction, including backchannels and other realtime social behaviour. Timo uses incremental processing to increase the flexibility and speed of SDSs and works on all aspects of interactive speech and language technologies, including recognition, synthesis, prosody, parsing, LMs, NLG and the architectures necessary to facilitate building large and incremental systems. Between joining CMU and completion of his PhD at Bielefeld University, Timo worked as a research and teaching associate at Universität Hamburg.
