Hello!

I am a theoretical physicist, interested in nonequilibrium statistical mechanics. I use analytical calculations and numerical simulations to answer questions inspired from soft and living matter. Find out more about my research interests and my publications.

I am a CNRS permanent researcher (chargé de recherche), and a member of PHENIX lab (Physical chemistry of electrolytes and interfacial nanosystems), hosted by Sorbonne Université (campus Pierre-et-Marie-Curie, Paris 5ème).
