Stefan Savage is a UCSD computer science professor specializing in computer security issues (especially worms, viruses, botnets, intrusion detection and denial-of-service attacks), wireless networking, and operating system kernel design. He joined the UCSD Jacobs School Computer Science and Engineering faculty in January 2001. He also serves as director of the Collaborative Center for Internet Epidemiology and Defenses (CCIED), a collaboration between UCSD and the International Computer Science Institute, one of four federally funded NSF CyberTrust Research Centers. He received his Ph.D. from the University of Washington, where he focused both on network protocol design and operating system structuring. Savage was a co-founder of Seattle-based startup Asta Networks, which specialized in denial-of-service defenses, and of San Diego-based NetSift Inc, which developed high-speed network-based worm defenses (recently acquired by Cisco Systems). He continues to provide regular guidance to the public and private sectors relating to Internet security. His current research interests include automated network monitoring and defenses and a variety of problems related to 802.11-based wireless network design.
