Susan Landau works at the intersection of cybersecurity, national security, law, and policy. Her insights on encryption policy, law-enforcement requirements for embedding surveillance within communication infrastructures, and securing private-sector telecommunications have deeply influenced policy makers and scholars.

Her new book, "Listening In: Cybersecurity in an Insecure Age", will be published by Yale University Press in November 2017. Landau's book "Surveillance or Security? The Risks Posed by New Wiretapping Technologies" (MIT Press) won the 2012 Surveillance Studies Book Prize, while "Privacy on the Line: The Politics of Wiretapping and Encryption" (MIT Press), co-authored with Whitfield Diffie, 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 has testified before Congress, written for the Washington Post, Science, and Scientific American, and frequently appeared on NPR and BBC.

Bridge Professor at the Fletcher School of Law and Diplomacy and School of Engineering, Department of Computer Science, Tufts University and Visiting Professor in Computer Science at University College London, Landau has been a senior staff Privacy Analyst at Google, a Distinguished Engineer at Sun Microsystems, and a faculty member at Worcester Polytechnic Institute, the University of Massachusetts Amherst and Wesleyan University.

Landau was inducted into the Cybersecurity Hall of Fame in 2015. She was a 2012 Guggenheim fellow, a 2010-2011 fellow at the Radcliffe Institute for Advanced Study, and the recipient of the 2008 Women of Vision Social Impact Award; she is also a fellow of the American Association for the Advancement of Science and the Association for Computing Machinery.
