Looking for excellent full-time or part-time graduate research students
I am looking for excellent full-time or part-time graduate students to research cutting edge topics in
networking and cyber security.
Please email me if you are interested in these or related topics.
Theory of Distributed Computing (unrelated to cyber security)
Internet of Things: Security and Performance aspects
Attack Resilient and Efficient DNS infrastructure
An AI-based Graphics Anti-Phishing Platform for zero-day Phishing Campaigns detection
My research interests span from distributed systems to tightly coupled multiprocessors. In
particular, I am interested in the theoretical study of asynchrony and its effects in systems (both
shared memory and message passing based), in concurrent programming (concurrent data structures and
transactional memory), and in networking (network security, protecting against denial of service
attacks and routing). I often examine synchronization and coordination problems in these areas using
tools and models from theoretical computer science and related disciplines.
I received a B.A. degree from the Technion in Electrical Engineering in 1978, and
M.Sc and Ph.D. degrees from University of California Los-Angeles (UCLA) in 1983 and 1985
respectively, both in Computer Science. I was a Member of Technical Staff at AT&T
Bell-Labs from 1985 to 1989. In 1989 I joined the computer science department at
Tel-Aviv University. I was a consultant for AT&T research labs from 1989 to 2000.
In 2001 I founded
Riverhead Networks together with Anat bremler-Barr, Dan
Touitou, and Yuval Rachmilevitch. Riverhead Networks is the only company to
have succeeded in providing a solution to the
Distributed Denial of Service attacks
on the Internet. The Riverhead Guard, our flag product, protects thousands of sites
(including some from fortune-5, and many from fortune-500), keeping them up and running
despite massive multi Gbps attacks over long periods of time.
Riverhead was acquired by Cisco in 2004,
after which I remained a director in Cisco
until May of 2009. I have since then returned to a full time professorship position at Tel-Aviv
University. 2014 -- 2016 Head of the Blavatnik School of Computer Science Tel-Aviv University.
