About

Hi! I’m Julien, a post-doc working with Christian Hilbe at the Max Planck Institute for Evolutionary Biology. I did my PhD with Jean-Baptiste André, in the Cognitive Science Department of Ecole Normale Supérieure, and Jean-Louis Dessalles, in the Computer Science Department of Telecom Paris. I am originally trained in Mathematics, and have studied (in that order) Economics, International Relations, Social Sciences, and Cognitive Sciences.

I am a game theorist, with a strong penchant for the social and psychological sciences. I want to better understand human societies and cultures based on models that are grounded in psychological first principles. I have tackled questions such as the function of intermediaries, the reason why we seek revenge even for minor offenses, and the mechanism through which institutions enable large-scale cooperation.

I particularly enjoy interdisciplinary collaborations. I’m always looking to learn new things, and keen to make models that are relevant for non-modelers. I’m also keen to talk with other young or aspiring scientists, and offer my perspective when I can. Feel free to reach out!

Here’s a recent CV.
