My research is aimed at the study of scalability, dependability and security of networked
systems and applications. My interests include distributed computing, network security,
and network protocols. I have led several
aimed at developing new protocols and architectures for ensuring dependability of the Internet infrastructure in the presence of security attacks, hardware and software failures, and operational faults.
I served as Chair for Computer Science and Engineering from 2007 - 2011 and as Director of the Software Systems Lab from 1997 - 2000.
In late 2000, I co-founded Arbor Networks,
a network security company based on research conducted with my collaborators and former students
at the University of Michigan. I serve as Chairman of Arbor Networks until its acquisition by
Tektronix Communications, a division of
Danaher, in September, 2010.
