- 2018-…: Working group in Machine learning and optimization starting, gathering researchers from the Bézout Labex and from other institutions and schools from Paris-Est. This is of course open to all interested researchers.
- 2016-2018: Weekly working group on Min-max theory and computational geometry gathering researchers interested in geometry, analysis, algorithms, and computational geometry around the min-max techniques and waist inequalities. Expected to restart in 2018-2019, after the arrival of Marcos Cossarini at the end of November.
- 2014-2015: Weekly working group on Large random matrices.
- 2013-2014: Weekly working group on Algorithms, combinatorics, complexity, and convexity.
- 2011-2012: Joint working group on Applications of large random matrices to signal processing.
