Beverly Park Woolf, PhD, is a Research Professor in the School of Computer Science at the University of Massachusetts-Amherst. She is a fellow of the American Association of Artificial Intelligence and she develops intelligent tutors that model students’ cognitive knowledge and affective behavior. Her research combines technologies from artificial intelligence, networks, sensors, and multimedia along with theoretical understandings from fields such as cognitive science, developmental psychology and analyses of learning. She builds systems that represent knowledge taught and the learners’ skills and behavior; these systems use sensors and machine learning to model student affect, and to adjust problems to help individual students. Some of the tutors built by Dr. Woolf enable students to pass standard exams at a 20% higher rate. One system in particular, is used by more than 150,000 students per semester. Dr. Woolf published the book Building Intelligent Interactive Tutors along with over 200 articles. She is the lead author on the NSF report Roadmap to Education Technology in which forty experts and visionaries identified the next big computing ideas for education technology and developed a vision of how technology can incorporate deeper knowledge about human cognition to produce more effective instruction.  Dr. Woolf has delivered keynote addresses, panels and tutorials in more than 30 foreign countries. Woolf received a Ph.D. in Computer Science, an Ed.D. in Education, and a M.S. in Computer Science, from the University of Massachusetts, and a B.A. from Smith College.
