I am assistant professor in Statistics and Machine Learning at INSA Rouen Normandie, within the Department of Mathematics since September 2023. 

From 2019 to 2023, I was a research fellow at the University of Warwick, within the CoSInES project, whose principal investigator is Gareth Roberts

From 2016 to 2019, I did my PhD at ENSAE Paris, within the Department of Statistics of CREST, under the supervision of Nicolas Chopin and Arnak Dalalyan. I defended my PhD thesis in July 2019, my manuscript is available here.

In 2016, I graduated with a double M.Sc. degree, between ENSAE Paris and the Master MVA (Mathematics, Vision, Learning) at Université Paris Saclay.

My research themes relate to computational methods for statistics and machine learning. I have worked mainly on sampling algorithms, which provide tools for the numerical approximation of statistical estimators and machine learning predictors. This work addresses several challenges, such as measuring their accuracy, evaluating their computational complexities and studying their robustness. Their construction and study are connected to several mathematical fields, such as stochastic processes, optimal transport, numerical analysis and optimisation. An overall objective is to develop efficient and reliable algorithms, while making these easily accessible by practitioners.
