I am the founder of HSK level, a Chinese learning app.

Prior to that, I worked as a postdoctoral researcher at CREST where I developped algorithms for economic models.

I defended my PhD in applied mathematics and machine learning in June 2021, where I worked under the supervision of Prof. Marco Cuturi.

**June 27, 2022:**I gave a talk in the New Monge Problems seminar at the Université Gustave Eiffel near Paris.**May 11, 2022:**I gave a talk (slides in .pdf) at the Mokaplan team seminar at INRIA in Paris.**October 21–22, 2021:**I participated in the*Paris workshop on optimal transport with applications to economics and statistics*at Sciences Po Paris.**June 29, 2021:**I defended my PhD thesis (slides in pdf and the manuscript) at ENSAE Paris.**March 31, 2021:**I gave a talk at the EDMH PhD students seminar (video in French).**March 4, 2021:**I gave a talk at the Image, Optimization and Probability seminar at the Institut de Mathématiques de Bordeaux.

**August 28, 2020:**We received a**Notable Paper Award**at AISTATS 2020 for our paper*"Regularity as Regularization: Smooth and Strongly Convex Brenier Potentials in Optimal Transport"*.**August 26–28, 2020:**I presented our paper*"Regularity as Regularization: Smooth and Strongly Convex Brenier Potentials in Optimal Transport"*at AISTATS 2020.**July 12–18, 2020:**I presented our paper*"Regularized Optimal Transport is Ground Cost Adversarial"*at ICML 2020.**January 17, 2020:**I gave a talk (.key, .pdf) at the seminar day Learning meets Astrophysics at CEA in Saclay, France.**December 08–14, 2019:**I presented our paper*Regularity as Regularization: Smooth and Strongly Convex Brenier Potentials*at NeurIPS Optimal Transport and Machine Learning Workshop in Vancouver, Canada.**November 20, 2019:**I gave an introductory lecture on optimal transport at the seminar Stat·Eco·ML in Palaiseau, France.**November 05, 2019:**I gave a talk (.key, .pdf) at Le Séminaire Palaisien in Palaiseau, France.**August 26–31, 2019:**I participated in, and gave a tutorial (notebooks, video) at Machine Learning Summer School in Moscow, Russian Federation.**July 07–19, 2019:**I participated in, gave a talk (.pdf) and presented a poster (.pdf), in Saint-Flour Probability Summer School in Saint-Flour, France.**June 24–28, 2019:**I participated in the workshop People in Optimal Transportation and Applications in Cortona, Italy.**June 09–15, 2019:**I presented (poster and 20-minute oral) our paper*"Subspace Robust Wasserstein Distances"*at ICML 2019 in Long Beach, USA.**March 25–29, 2019:**I presented a poster (.pdf) at the workshop Optimization and Statistical Learning in Les Houches, France.

I've been working on *algorithmic optimal transport (OT)*, with applications to *machine learning* and *economics*. My work focuses on designing algorithms for OT problems as well as OT tools that are more robust to the curse of dimensionality, to data corruption or noise, so that OT can be efficiently applied to real data problems.

Voici une introduction au transport optimal extraite d'un séminaire de vulgarisation que j'ai donné à destination des doctorants de l'École doctorale Hadamard en mars 2021.

My PhD manuscript can be found here.
