Michel Fruchart
I am a CNRS researcher at Gulliver in ESPCI and PSL University. My research interests center on soft and hard condensed matter physics, including active matter, nonlinear dynamics, statistical physics, and hydrodynamics. Recent works focus on the effect of non-reciprocity on many-body systems, ranging from phase transitions to turbulence.
Before that, I was a postdoctoral fellow at the University of Chicago and at the Lorentz Institute for theoretical physics, working in the group of Vincenzo Vitelli. 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 with David Carpentier and Krzysztof Gawędzki.
