About

Hi! I’m Julien. I study the diversity of human social organization — why societies differ in their norms, institutions, and the scope of trust and moral obligation. I use mathematical models to identify the adaptive trade-offs that shape different forms of social organization, and computational models to study how people reason about norms and cooperation.

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.
