He is also the scientific co-leader of the Fraunhofer Cybersecurity Center at Hebrew University. His research interests focus on the protocols/mechanisms that make the Internet tick (e.g., for routing, traffic management). He is interested in the design and analysis of practical (Inter)network architectures and protocols with provable guarantees (failure-resilience, optimality, security, incentive compatibility, and beyond). He is also broadly interested in the the interface of computer science, economics, and game theory (e.g., dynamic interactions in economic and computational environments, incentive-compatible computation, computational auctions, and more).
