Barbara J. Grosz is Higgins Professor of Natural Sciences in the School of Engineering and Applied Sciences at Harvard University. From 2007-2011, she served as Interim Dean and then Dean of the Radcliffe Institute for Advanced Study, and from 2001-2007 she was the Institute’s first dean of science, designing and building its science program. Grosz is known for her seminal contributions to the fields of natural-language processing and multi-agent systems. She developed some of the earliest computer dialogue systems and established the research field of computational modeling of discourse. Her work on models of collaboration helped establish that field and provides the framework for several collaborative multi-agent systems and human computer interface systems. She is an elected member of the National Academy of Engineering, the American Philosophical Society, and the American Academy of Arts and Sciences and a fellow of the Association for the Advancement of Artificial Intelligence (AAAI), the Association for Computing Machinery, and the American Association for the Advancement of Science. In 2009, she received the ACM/AAAI Allen Newell Award for “fundamental contributions to research in natural language processing and in multi-agent systems, for her leadership in the field of artificial intelligence, and for her role in the establishment and leadership of interdisciplinary institutions.” In 1993, she became the first woman president of the AAAI. Grosz is also widely respected for her contributions to the advancement of women in science. She was a member of the National Academies’ committee that produced the report “Beyond Bias and Barriers” in 2006, served as chair of Harvard University’s Task Force for Women in Science and Engineering in 2005, and served as chair of the Standing Committee on the Status of Women when it issued the 1991 Report on Women in the Sciences at Harvard.
