Research interests

I work on mathematical, algorithmical, and computational aspects of mathematical optimization. An originality of my research is the application of continuous optimization techniques to discrete optimization problems: check out the overview of my HdR defence slides (in French). My current reserach can be included in the broad topic of algorithmic foundations of data science and AI.

Research topics

  • Nonsmooth optimization: theory and algorithms
  • Distributed optimization for machine learning
  • Decomposition methods and stochastic optimization for electricity generation

Highlight : BiqCrunch 2.0 available !

New release of our software for solving quadratically-constrained BInary Quadratic optimization problems (BIQ). It outperforms state-of-the-art on the hardest combinatorial optimization problems, see more on the BiqCrunch web site. We gave an extended tutorial (15h) on BiqCrunch and semidefinite programming for combinatorial optimization at the summer school JPOC in Paris XIII.

Highlight : Conference SMAI-MODE

Our team organized the 2018 edition of the French Days on Optimization and Decision Science (Journées SMAI-MODE 2018). This edition held, from March 28 to March 30, 2018, in a conference center, in the heart of the Vercors Massif (about one hour from Grenoble). The scientific program was rich with talks and spotlight/posters on optimization, game theory, control, and decision science in general. The social program was also quite good too with snow/nature activities, biathlon, special "mountain" diner, "oberwolfach" lunch, cheese/poster session...
