About me

I am an associate professor (maître de conférences) of physics at Sorbonne Université and research the statistical physics of soft active matter, using numerical and theoretical tools, at the laboratoire de Physique et Mécanique des Milieux Hétérogènes (PMMH) in Paris, France.

My current research interests revolve around the structure and dynamics of dense active matter, including

  • emergent collective motion (active turbulence, dynamical heterogeneities),
  • structural ordering and its interplay with collective motion,
  • control of active materials.
There are two open master internship positions in my group to track topological defects in active solids and study active turbulence with deformable self-propelled particles. Please do not hesitate to contact me for more information!

IntCha26 conference in Cargèse

We are organising the conference Interdisciplinary Challenges in the Physics of Complexity and Life 2026 (IntCha26) between the 20th and 24th of April 2026 at the Institut d'Études Scientifiques in Cargèse (Corsica). It aims to connect young researchers from diverse backgrounds at the interface between the physics of complex systems and biology. We will cover a broad variety of topics,

  • transport across scales,
  • data-driven modelling,
  • active matter,
  • AI and machine learning,
  • cells and tissues,
  • animal behaviour,
  • ecology and evolution,
  • non-equilibrium systems.

You can find more information on the conference website intcha26.sciencesconf.org. Applications close on 15th December!

A big thanks to all those who make the fruit of their labour freely available to all on the internet, those who publish open access papers, those who develop free software, and those who share their knowledge, skills, and creativity on wikis and forums. A great part of my projects — both personal and academic — could not have been realised without you.
