CV
Susan Landau is a faculty member in the Worcester Polytechnic Institute Department of Social Science and Policy Studies, where she works on cybersecurity, privacy, and public policy. She has been a senior staff Privacy Analyst at Google, a Distinguished Engineer at Sun Microsystems, a faculty member at the University of Massachusetts at Amherst and Wesleyan University and has held visiting positions at Harvard, Cornell, and Yale, and the Mathematical Sciences Research Institute. She is the author of Surveillance or Security? The Risks Posed by New Wiretapping Technologies (MIT Press, 2011), and co-author, with Whitfield Diffie, of Privacy on the Line: The Politics of Wiretapping and Encryption (MIT Press, 1998, rev. ed. 2007). She testified for the House Judiciary Committee on security risks in wiretapping and for the House Science Committee on Cybersecurity Activities at NIST's Information Technology Laboratory. A 2012 Guggenheim fellow and 2010-2011 fellow at the Radcliffe Institute for Advanced Study, Landau is the recipient of the 2008 Women of Vision Social Impact Award, and is also a fellow of both the American Association for the Advancement of Science and the Association for Computing Machinery.

  Biographical Information

Susan Landau is Professor of Cybersecurity Policy in the Department of Social Science and Policy Studies at Worcester Polytechnic Institute. Landau has been a Senior Staff Privacy Analyst at Google and a Distinguished Engineer at Sun Microsystems . Her book Surveillance or Security? The Risks Posed by New Wiretapping Technologies (MIT Press) won the 2012 Surveillance Studies Book Prize. At Sun, Landau also worked on digital rights management, where she helped establish Sun's stance on DRM, privacy and security issues in federated identity management, and worked on cryptography and export control. Before joining Sun, Landau was a faculty member at the University of Massachusetts and Wesleyan University, She also held visiting positions at Harvard, Yale, Cornell, and the Mathematical Sciences Research Institute at Berkeley and spent many summers teaching at Hampshire College Summer Studies in Mathematics, a program for high-ability high school students (cf. Supporting a National Treasure).

Landau's previous research in algebraic algorithms included a number of polynomial-time algorithms to problems previously known only to have exponential-time solutions; this work had applications to symbolic computation, cryptography, and computational geometry. During the 1990s Crypto Wars and the battle over cryptographic export control, Landau shifted her interest to policy issues. Landau and Whitfield Diffie wrote Privacy on the Line: The Politics of Wiretapping and Encryption (MIT Press), which won the 1998 Donald McGannon Communication Policy Research Award, and the 1999 IEEE-USA Award for Distinguished Literary Contributions Furthering Public Understanding of the Profession (revised edition, 2007). Landau is also primary author of the 1994 Association for Computing Machinery report Codes, Keys, and Conflicts: Issues in US Crypto Policy.

In recent years Landau has focused on the security risks of embedding surveillance within communications infrastructures. She has briefed members of the U.S. and European governments, written numerous articles on the issues, including for the Washington Post, Scientific American, the Chicago Tribune, and the Christian Science Monitor, and participated in several industry reports on the issue. She has also appeared on NPR a number of times (including on All Things Considered, On the Media, and Talk of the Nation), and has published in a number of venues, including IEEE Security and Privacy, Communications of the ACM, National Security Journal, Journal of Telecommunications and High Technology Law, as well as in technical conferences and workshops. With Sun CTO Greg Papadopoulos, Landau helped establish Sun's principles on digital-rights management, including ``All creators are users, and many users are creators,'' and ``Respect for users' privacy is essential.'' Sun's DRM project, DReaM, provided support for fair use, the only DRM system to do so. Landau also worked on privacy and security aspects of the Liberty Alliance federated identity management system.

Landau serves on the Computer Science and Telecommunications Board of the National Research Council and as associate editor in chief for IEEE Security and Privacy. She served the advisory committee for the National Science Foundation's Directorate for Computer and Information Science and Engineering, the National Institute of Standards and Technology's Information Security and Privacy Advisory Board, and the Commission on Cyber Security for the 44th Presidency, established by the Center for Strategic and International Studies. She was section board member for Communications of the ACM from 2008-2014 and as an associate editor of the Notices of the American Mathematical Society from 1994-2001.

Landau is active in issues related to women in science. She started researcHers, a mailing list for women computer science researchers in academia, industry and government labs and with Elaine Weyuker, created the ACM-W Athena Lectureship, an award celebrating outstanding women researchers. In 2008 Landau co-chaired the MIT Celebration of Women in Math meeting. She has served on the executive committee of ACM-W and the Computing Research Association Committee on the Status of Women in Computing Research (CRAW).

A 2012 Guggenheim fellow and 2010-2011 fellow at the Radcliffe Institute for Advanced Study, Landau is the recipient of the 2008 Women of Vision Social Impact Award, and is also a fellow of the American Association for the Advancement of Science and the Association for Computing Machinery. She received her PhD from MIT (1983), her MS from Cornell (1979), and her BA from Princeton (1976).
