Joan Feigenbaum is the Grace Murray Hopper 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 principal in several high-profile activities, including the NSF-funded PORTIA Project and the ONR-funded SPYCE Project. She currently serves on the Scientific Council of the Web Sciences Research Institute, as Vice Chair of the ACM Special Interest Group on Electronic Commerce (Sigecom), and as a Steering-Committee Member of the NetEcon Workshop.
