Dr. Sean Peisert is an expert in computer and network security. He works as a computer security research and development lead, professor, and director of operational cybersecurity.

His current focus includes “big data” security, security in high-performance computing environments, security in high-throughput networks, and cybersecurity for power grid control systems. His recent R&D includes two provisional patents: one relating to security in data center and high-performance computing environments, and one relating to de-identifying data while maintaining usefulness of that data. His work on power grid control system security also has numerous power utility, vendor, and consulting partners.


Dr. Peisert occasionally serves as a consultant to companies and organizations in areas of software, system, and network security strategy and design, and is available as a subject-matter expert advising executives, investors, and entrepreneurs developing computer security technologies.

His view of security is as an “enabling” capability that, when done properly, can allow organizations to operate more effectively, and not merely a set of practices and technologies that impose financial costs and burdens on a company’s employees and other users.

He also occasionally serves as an expert witness in computer forensics cases.


Dr. Peisert received his Ph.D., Masters, and Bachelors degrees in Computer Science from the University of California, San Diego. His background includes experience in computer security at Lawrence Berkeley National Laboratory, the Corporation for Education Network Initiatives in California (CENIC), the San Diego Supercomputer Center, and as an adjunct associate professor of computer science and faculty member in the computer science, forensic science, and health informatics graduate programs at the University of California, Davis.

He has also worked in both R&D and operational aspects of computer security and networking. His R&D work typically focuseses on developing processes and techniques that can provide meaningful, useful, and measurable improvements to and/or insights regarding computer security. As Chief Cybersecurity Strategist for CENIC, he develops cybersecurity strategy and implements cybersecurity practices for CENIC’s enterprise and external network (CalREN).

In 2007, he was honored as a Research Fellow by the Institute for Information Infrastructure Protection, funded by the U.S. Department of Homeland Security.

He has taught university courses in security for health informatics, computer forensics, “insider” threats, and critical systems, advises numerous graduate students, and has led sponsored research and development projects covering a wide space of computer security including intrusion detection systems; forensic tools and techniques; data sanitization and anonymization; fault tolerance; electronic voting; SCADA/industrial control system security; and “insider” threats. He has published more than 60 peer-reviewed papers, invited articles and book chapters, and technical reports, and has given over 75 invited talks and tutorials in a variety of venues.

He is actively involved with the computer security community, as well as communities to which he studies, develops, and applies computer security techniques, including legal, medical, financial, and public policy organizations, and other organizations operating critical infrastructure.

He has led numerous cybersecurity-related working groups, including two workshops in 2015 for the U.S. Department of Energy’s Office of Advanced Scientific Computing Research to establish key needs and directions for a high-performance computing cybersecurity research and development program. He also co-led the Open Science Cyber Risk Profile working group. Prior to the 2008 U.S. presidential election, he co-authored a guide, distributed at the time via the American Bar Association, to help election officials understanding how computer forensic techniques can be applied to issues with electronic voting machines and related systems.

He is vice chair of the IEEE Computer Society Technical Committee on Security & Privacy; is an editorial board member of IEEE Security & Privacy magazine; a steering committee member and past general chair of the New Security Paradigms Workshop; a steering committee member and past program co-chair of the Workshop on Cyber Security Experimentation and Test (CSET); and is past general chair for the 2015 IEEE Symposium on Security and Privacy, the flagship conference for computer security research.
