She has authored more than 200 research papers on online privacy, usable security, and other topics. She has played a key role in building the usable privacy and security research community, having co-edited the seminal book Security and Usability (O'Reilly 2005) and founded the Symposium On Usable Privacy and Security (SOUPS). She also chaired the Platform for Privacy Preferences Project (P3P) Specification Working Group at the W3C and authored the book Web Privacy with P3P (O’Reilly 2002). She has served on a number of boards and working groups, including the Electronic Frontier Foundation Board of Directors, the Computing Research Association Board of Directors, the Aspen Institute Cybersecurity Group, and on the editorial boards of several journals.

In her younger days she was honored as one of the top 100 innovators 35 or younger by Technology Review magazine. More recently she was elected to the ACM CHI Academy, named an ACM Fellow for her contributions to usable privacy and security research and education, and named an IEEE Fellow for her contributions to privacy engineering. She has also received an Alumni Achievement Award from the McKelvey School of Engineering at Washington University in St. Louis, the 2018 ACM CHI Social Impact Award, the 2018 International Association of Privacy Professionals Privacy Leadership Award, and (with colleagues) the 2018 IEEE Cybersecurity Award for Practice.

She was previously a researcher at AT&T-Labs Research and taught in the Stern School of Business at New York University. She holds a doctorate in Engineering and Policy from Washington University in St. Louis. In 2012-13 she spent her sabbatical as a fellow in the Frank-Ratchye STUDIO for Creative Inquiry at Carnegie Mellon University where she worked on fiber arts projects that combined her interests in privacy and security, quilting, computers, and technology.
