About me

Since 2024, I have been working as a Data & AI scientist at Kaukana Ventures.

From November 2020 to November 2023, I was a PhD student in applied mathematics at LPSM, Université Paris Cité (Paris 7) under the supervision of Stéphane Gaïffas and Emmanuel Bacry.

I defended my PhD thesis titled “Robust Algorithms an Other Contributions to Machine Learning” on December 12th 2023. You can find the manuscript here and the slides here.
