I am a theoretical physicist interested in the study of nonequilibrium statistical mechanics and its application to living matter. My current research work particularly focuses on emergent self-organized behaviors of living and nonliving active matter systems, such as the transition to collective motion or Bose-Einstein-like condensation due to motility inhibition.

I obtained my Ph.D. from Université Paris-Saclay in 2018 working with Hugues Chaté. After occupying a short postdoctoral position in the former group of Prof. Masaki Sano at Tokyo University, I joined the Living Matter Physics Department in 2019 as a postdoctoral researcher and was promoted to group leader in 2021.
