Raphaël Barboni

Postdoctoral fellow, Bocconi University

I am currently a postdoctoral fellow at the Bocconi Institute for Data Science and Analytics (BIDSA), mentored by Giacomo Zanella. This position is funded by the ERC project "Provable Scalability for high-dimensional Bayesian Learning".

Before, I did my Ph.D. at the Department of Mathematics and Applications of ENS Ulm in Paris, working under the supervision of Gabriel Peyré and François-Xavier Vialard. This work was part of the Noria and Wolf ERC projects.

My thesis manuscript is available here.

Research Interests

My research field is theoretical Machine Learning: I study the mathematical properties of large-scale algorithms for solving problems in optimization, sampling and learning.

In my Ph.D., I used tools from the theory of optimization, optimal control and optimal transport to study the convergence of gradient based algorithm in the training of overparameterized neural network architectures such as deep ResNets.
