Michel Fruchart


I am a Kadanoff-Rice postdoctoral fellow at the University of Chicago, working in the group of Vincenzo Vitelli in the James Franck Institute. I work on theoretical soft and hard condensed matter physics. My current interest is mostly focused on the field of topological insulators and geometric phases.

Before that, I was a postdoctoral researcher at the Lorentz Institute for theoretical physics. Even before, I worked on topological phases of periodically driven crystals as a PhD student at the Laboratoire de Physique of the ENS de Lyon, under the supervision of David Carpentier and Krzysztof Gawędzki.

If you read French, I invite you to read a popular science article that I wrote for SFP's Le Rayon with Clément Tauber: De la lumière à sens unique : métamatériaux topologiques et guides d'onde unidirectionnels.
