Biography, Education and Training

• Marilyn Walker, is  a Research Professor  appointment in the Computational Media Department and an emerita Professor of the Computer Science and Engineering Department at UC Santa Cruz. She is a fellow of the Association for Computational Linguistics (ACL), in recognition of her for fundamental contributions to statistical methods for dialog optimization, to centering theory, and to expressive generation for dialog. She is the Founder of the Natural Language Processing Professional M.S. Program at UCSC Silicon Valley. Her current research includes work on interactive narrative and story telling, computational models of character personality and style,  models of dialogue interaction and conversational agents, and statistical methods for training the dialogue manager and the language generation engine for either task oriented, social, or storytelling dialogue systems. Before coming to Santa Cruz in 2009, Walker was a Professor of Computer Science at the University of Sheffield. From 1996 to 2003, she was a principal member of the research staff at AT&T Bell Labs and AT&T Research, where she worked on the AT&T Communicator project, developing a new architecture for spoken dialogue systems and statistical methods for dialogue management and generation. Walker has published more than 300 papers and has 9 U.S. patents.  Her H-index is currently 79. She earned a B.A. in Computer and information science at UC Santa Cruz with Honors, an M.S. in Computer Science at Stanford University, and an M.A. in linguistics and Ph.D. in Computer and Information Science at the University of Pennsylvania.
