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, Mathematics of Operations Research, Theoretical Economics, Journal of Economic Theory.

At HEC, he teaches managerial economics, microeconomics and game theory to  HEC 1st year, the Master of Financial Economics, the Master in Economics of IP Paris-HEC  and the Phd Program.

Tristan Tomala is associate editor for Operations Research Letters (Area Editor), Dynamic Games and Applications and Theory and Decision.
