Welcome!

I am a French PhD student working on Optimization Algorithms in Sequential Learning, supervised by Aurélien GARIVIER at UMPA (Lyon 🇫🇷) and Gilles STOLTZ at LMO (Orsay 🇫🇷), since September 2020. Physically I mainly work from Lyon. I am also teaching exercice sessions to undergraduate students at ÉNS Lyon and I am coordinating the PhD student seminar of the UMPA and the ICJ.

What if we voted differently?
I present a reflection on current voting systems to high school students. This leads to a new voting system called the Majority Judgment, Je présente à des lycéens une réflexion sur nos systèmes de votes actuels qui va nous mener à un nouveau système de vote, le jugement majoritaire, which resolves many of the paradoxes of today’s systems.
