I hold B.Sc. degrees in mathematics and computer science (Magna Cum Laude), an LL.B degree in law, and M.Sc (Summa Cum Laude) and P.hD degree (with distinction) in computer science, all from Tel Aviv University. In 2001 I co-founded Riverhead Networks Inc., a company that provides systems to protect from Denial of Service attacks. I was the chief scientist of the company. The company was acquired by Cisco Systems in 2004. My research interests are in computer networks and distributed computing. My current works are focused on Designing routers and protocols that support efficient and reliable communication.
