Joan Feigenbaum is the Henry Ford II Professor of Computer Science at Yale University. She received a BA in Mathematics from Harvard and a Ph.D. in Computer Science from Stanford. Between finishing her Ph.D. in 1986 and starting at Yale in 2000, she was with AT&T, where she participated very broadly in the company's Information-Sciences research agenda, e.g., by creating a research group in Algorithms and Distributed Data, of which she was the manager in 1998-99. Professor Feigenbaum's research interests include Internet algorithms, computational complexity, security and privacy, and digital copyright. While at Yale, she has been a principle in several high-profile activities, including the NSF-funded PORTIA Project and the ONR-funded SPYCE Project. Her current and recent professional service activities include membership in the NAS Computer Science and Telecommunications Board, Program Chair for the 2002 ACM Workshop on Digital Rights Management, Program Co-Chair for the 2004 ACM Conference on Electronic Commerce, Conference Chair for the 2006 ACM Conference on Electronic Commerce, Executive-Committee Member-at-Large of the ACM Special Interest Group on Algorithms and Computational Theory (Sigact), and Vice Chair of the ACM Special Interest Group on Electronic Commerce (Sigecom).
