Biography

Tristan Tomala was a student at ENSAE before doing a Ph.D. on game theory (defended in 1996) at University Paris I. Prior to joining HEC Paris, he was assistant professor (maitre de conférences) at University Paris Dauphine. His research interests are about the various aspects of information and communication in dynamic games. He studies strategic information transmission in repeated games using information theory, graph theory and cryptography and has  also a special interest for information and communcation networks.

His recent works are published in Games and Economic Behavior (2014), Mathematics of Operations Research (2013), Theoretical Economics (2012), Journal of Economic Theory (2011). At HEC, he teaches managerial economics in HEC 1st year and game theory in the Masters of Business Economics  and in the Master of Economics of Paris Saclay.

Tristan Tomala is associate editor for  Dynamic Games and Applications, International Journal of Game Theory, Operations Research Letters and Theory and Decision.
