About me

I am a postdoc researcher at Weierstrass Institute, Berlin. I obtained my Ph.D. at the University of Lyon in October 2021 under the joint supervision of Filippo Santambrogio and Andrei Sobolevski. My main research interests are optimal transportation theory, mathematical statistics, learning theory, convex optimization, and their interactions.

Online seminar

On the interactions between Statistics and Geometry

Together with Victor-Emmanuel Brunel, Austin Stromme, and Quentin Paris, we organize a monthly online seminar on Geometry and Mathematical Statistics. The aim is to promote communication between the two fields. Announcements of upcoming talks and records of the previous ones can be found on the seminar page.
