I'm a Senior Computer Scientist at USC's Information Sciences Institute, responsible for overseeing teams to develop and execute research ideas. I'm principally responsible for the operation and management of the Internet’s b.root-servers.net DNS critical infrastructure, which handles 1/13th of all the world’s top level DNS requests. I'm also the principal representative for USC/ISI's DNS root server in the Root Server System Advisory Committee (RSSAC) in the multi-stakeholder Internet Corporation for Assigned Names and Numbers (ICANN) organization, where I am also a member of the ICANN Board of Directors.
My research focuses on cybersecurity generally, intrusion detection specifically, internet standards development and research programs to enhance the DNS and other Internet protocols. My currently active research projects are listed below.
I have been actively participating for over 25 years in the IETF open standards body that defines internet protocols, and currently serve as a member of the Internet Architecture Board (IAB).
