Joan Feigenbaum is Department Chair and Grace Murray Hopper Professor of Computer Science and Professor (Adjunct) of Law 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 security, privacy, anonymity, and accountability; Internet algorithmics; and computational complexity. While at Yale, she has been a principal in several high-profile activities, including the DARPA-funded DISSENT project, the NSF-funded PORTIA project, and the ONR-funded SPYCE project. Her current and recent professional activities include service as the Program Chair of the 2013 ACM Symposium on Theory of Computing and membership on the Editorial Board of the ACM Transactions on Economics and Computation and the Steering Committee of the NetEcon Workshop. Professor Feigenbaum is a Fellow of the ACM, a Fellow of the AAAS, a Member of the Connecticut Academy of Science and Engineering, and a Connecticut Technology Council Woman of Innovation. In 1998, she was an invited speaker at the International Congress of Mathematicians.
