About

Hi! I’m Julien. I study large-scale cooperation and the psychology that underpins it—how human minds shape the rules, norms, and institutions that allow cooperation to extend beyond small groups.

I am currently based in Boston, collaborating with researchers in Josh Tenenbaum’s group at MIT and Fiery Cushman’s group at Harvard, and working remotely with Pat Barclay at the University of Guelph. Previously, I was a postdoc with Christian Hilbe (Max Planck Institute for Evolutionary Biology). I did my PhD with Jean-Baptiste André (ENS-PSL) and Jean-Louis Dessalles (Telecom Paris).

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.
