Given a system of multiple agents (such as a transportation system of multiple users, a market of competing product portfolios), we quantify the overall system performance when the system is at an equilibrium state. Furthermore, we research into introduction of incentive-compatible mechanisms to the systems to improve system performance at equilibrium.

A related interest is in game theoretic approaches to security on networks: either patrolling networks against intrusion or searching networks for hidden devices. In these games one player is a mobile "searcher", while the other is a stationary "attacker" or "hider". More generally, there is an interest in what are known as search games.
