Paula Hawthorn, Ph.D., Co-Chair

Dr. Hawthorn received her Ph.D. in Electrical Engineering and Computer Science from the University of California in 1979. Her thesis topic was on the performance of database systems. She has spent much of her career as a manager of database development, including Vice-President of Software Development for start-ups such as Britton Lee and Illustra, and both management and individual contributor positions at Hewlett-Packard (working on database performance issues) and Lawrence Berkeley National Laboratory. She is now mostly retired, with occasional consulting and continuing involvement with U.C. Berkeley.

Barbara Simons, Ph.D., Co-Chair

Dr. Simons earned her Ph.D. from U.C. Berkeley and was a computer science researcher at IBM Research, where she worked on compiler optimization, algorithm analysis, and scheduling theory. A former President of the Association for Computing Machinery (ACM), Dr. Simons founded ACM's U.S. Public Policy Committee (USACM) and served for many years as chair or co-chair of USACM. She was a member of the National Science Foundation panel on Internet Voting, the security peer review group for the DoD's Internet voting project (SERVE), and the President's Export Council's Subcommittee on Encryption. She is on several boards of directors, including the U.C. Berkeley Engineering Fund and the Electronic Privacy Information Center, as well as the Advisory Board of the Oxford Internet Institute and the Public Interest Registry's .ORG Advisory Council. She has testified before both the U.S. and the California legislatures. Dr. Simons is currently co-authoring a book on voting machines and related issues.

He has served on many National Research Council (NRC) study committees and is a member of the Department of Homeland Security's Science and Technology Advisory Committee. He has been a member of the Internet Architecture Board and co-director of the Security Area of the Internet Engineering Task Force.

Chris Clifton, Ph.D.

Professor Clifton has a Ph.D. in Computer Science from Princeton University, and Bachelor's and Master's degrees from the Massachusetts Institute of Technology. He first worked on reliability and availability of database systems at IBM Research in the 1980s. He also worked on data mining and database security issues while at the MITRE Corporation and, more recently, has been leading research on privacy-preserving data mining since joining the faculty of Purdue University.

Lillie Coney

Ms. Coney is Associate Director with the Electronic Privacy Information Center (EPIC). Her issue areas include nanotechnology, surveillance, children's privacy, civil rights and privacy, coalition development, spectrum, census, and electronic voting. Ms. Coney also serves as Coordinator of the recently established National Committee on Voting Integrity (NCVI). NCVI was created in 2003 in response to growing concerns about the reliability of electronic voting systems.

Robert Gellman

Robert Gellman is a privacy and information-policy consultant in Washington, D.C. He advises companies, government agencies, and other institutions on how to address privacy concerns on the Internet, implement the federal medical-privacy rules, and integrate privacy law and policy in their national and international operations.
