I am/was a member of:
- The Société Mathématique de France (and through it the European Mathematical Society).
- The GDR Algebraic Topology and Applications.
- (2014–2015) The ANR project “Algebraic Homotopy, Operads and Grothendieck–Teichmüller groups” (HOGT) coordinated by Benoit Fresse.
- (2021–2024) The ANR project “Higher Algebra, Geometry, and Topology” (HighAGT) coordinated by Bruno Vallette.
From January to June 2019, I organized a reading seminar on homological stability and the works of Galatius–Kupers–Randal-Williams with Mario Gonçalves Lamas following an idea of Muriel Livernet.
