Mostly coping with NP-hard combinatorial optimization problems. Also cryptography, random walks, and miscellaneous other stuff.
My CV (2012).
List of publications (2011).
Selected older publications on hardness of approximation, approximation algorithms and heuristics.
A short survey on my work on random walks.
My PHD thesis on alternative models for zero knowledge interactive proofs.
Some other publications that I like but do not fit in any of the other categories.
Technical reports, and unpublished work of some students who worked with me.
When operational, should lead to technical reports published by our faculty in the Weizmann Institute.
