      Doctor of philosophy (ph.d.) mathématiques appliquées

      I worked on Bayesian games, mechanism design, fairness, optimization and shift scheduling.My first paper was on a novel formulation of Bayesian games in terms of so-called return functions instead of strategies. This allowed for computations of approximated Bayesian-Nash equilibria.My second paper applied this formulation to heuristic Bayesian-incentive-compatible cake-cutting.My third paper addresses the normalization of utility functions through social comparisons of allocations… Show more I worked on Bayesian games, mechanism design, fairness, optimization and shift scheduling.My first paper was on a novel formulation of Bayesian games in terms of so-called return functions instead of strategies. This allowed for computations of approximated Bayesian-Nash equilibria.My second paper applied this formulation to heuristic Bayesian-incentive-compatible cake-cutting.My third paper addresses the normalization of utility functions through social comparisons of allocations. This led to new definitions of fairness, which, notably, involve social networks.My fourth paper applied such ideas to shift-scheduling optimization with employee preferences. Show less

      Aug 2016 - Jul 2022
      Science researcher & communicator

      My research interest revolves around robust, strategyproof and aligned large-scale learning algorithmic systems. My end goal is to provide the best-possible technical tools and mathematical guarantees to robustly learn humans' deep preferences. I hope that this can encourage big techs to robustly align their algorithms with the interests of all of humanity. This is best explained in my book #LeFabuleuxChantier.https://laboutique.edpsciences.fr/produit/1107/9782759824304/Le%20fabuleux%20chantierI regularly give talks, appear on medias, write books and make videos. I am responsible in particular for the EPFL IC School's science communication channels. Wandida aims to deliver quality videos explaining key concepts of computer science, mathematics and physics. ZettaBytes interviews reseachers, with further explanations provided by myself. I am also in charge of the Swiss "Concours Alkindi" cryptography competition for middle school students. Show less

      Book author

      My first book is "La formule du savoir", published by EDP Sciences in 2018, which was translated in English in 2020 as "The Equation of Knowledge", published by CRC Press. This book is a narrated introduction to Bayesianism, an epistemology that exclusively rests on applying the laws of probability.https://laboutique.edpsciences.fr/produit/1035/9782759822614/La%20formule%20du%20savoirhttps://www.routledge.com/The-Equation-of-Knowledge-From-Bayes-Rule-to-a-Unified-Philosophy-of-Science/Hoang/p/book/9780367428150My second book is "Le fabuleux chantier", co-written with Prof. El Mahdi El Mhamdi and published by EDP Sciences. The first part of the book describes the opportunities and pitfalls offered by artificial intelligence, and argues that it has become urgent to make information systems robustly beneficial for humanity. The second part argues that this great endeavor is extremely challenging, and that intuitively appealing solutions are likely to lead to very undesirable unintended side effects. Finally, the third part of the book sketches the outline of a program to solve the technical and socio-economical challenges.https://laboutique.edpsciences.fr/produit/1107/9782759824304/Le%20fabuleux%20chantierMy third book is "Turing à la plage", co-written with Prof. Rachid Guerraoui and published by Dunod. This book is a gentler introduction to artificial intelligence and computer science. It follows the footsteps of Turing's brilliant insights, and shows how they have been researched, developed and deployed in the recent years.https://www.dunod.com/sciences-techniques/turing-plage-intelligence-artificielle-dans-un-transat Show less
