Ph.D Thesis

On September 21st 2018, I defended my Ph.D. thesis on Statistical properties of barycenters in the Wasserstein space and fast algorithms for optimal transport of measures, under the supervision of Jérémie Bigot and Nicolas Papadakis, within the Institut de Mathématiques de Bordeaux, Université de Bordeaux, and for which I received the 2018 Jacques Neveu Prize.
