Evolutionary dynamics in strategic games; evolution of social norms and social preferences; behavioral and social structure in strategy revisions


Dr. Zusai is an active scholar in the area of evolutionary game theory, one of the most interdisciplinary research fields in game theory. While economists conventionally focus on equilibrium (competitive equilibrium, Nash equilibrium, etc.) as the final state of the world, evolutionary game theorists ask whether and how the decentralized economy/society is brought to an equilibrium despite complex strategic interdependence between choices of diverse actors. They formulate such adjustment processes mathematically by differential equations and stochastic processes. Among the fellow scholars in this area, Dr. Zusai’s research is distinguished by taking a variety of structural components in strategic decision making and social interactions into the general framework of evolutionary dynamics. Reflecting flexibility of the framework, his research interest ranges from philosophical questions about evolution of social norms and sociological investigations about racial segregation to engineering applications to decentralized multi-agent systems.

Dr. Zusai’s research papers are published in first-tier leading journals in economic theory and game theory, such as Journal of Economic Theory and International Journal of Game Theory, as well as other respectable field journals. He gave research presentations at international large conferences such as Game Theory Society World Congress, Stony Brook International Game Theory Festival as well as regional and field-special conferences and invited seminars in the U.S., Europe and Asia. While Dr. Zusai defines himself as a game theorist on the economics side, he is recently nominated as a non-anonymous contributor for MathSciNet, a review database of journal articles and books in mathematics and mathematical sciences (including economic theory) hosted by American Mathematical Society.

At Temple, Dr. Zusai is teaching “mathematics for economics” and microeconomic/game theory both for undergraduate and graduate students. He launched Econ 3519 Game Theory and Strategic Behavior as the introductory course on game theory; he welcomes Temple undergraduates from a wide range of disciplines. Prior to joining Temple in 2011, he received Ph.D. and M.S. in economics from University of Wisconsin-Madison and M.A and B.A. in economics from University of Tokyo.
