My research focus is mechanism design or essentially any topic that captures the border between computer science theory, game theory and microeconomic theory. Among the topics I work on are: Combinatorial Auctions & Markets, Sponsored Search Mechanisms, Social Networks, Coalitions, Information Markets, Rational Cryptography, Rational Distributed Computation, Online Algorithms and Computation, and Approximation Algorithms.
