Since April 2024, I have been a postdoctoral researcher in the High-Dimensional Causal Analysis Team at RIKEN, under the supervision of Masaaki Imaizumi, working on theoretical machine learning and high-dimensional statistics.
Before that, I was a postdoctoral researcher in the Imperfect Information Learning Team from 2023 to 2024. Prior to that, I completed my Ph.D. at Inria Lille - Nord Europe, as part of the MODAL team, supervised by Christophe Biernacki and Hemant Tyagi. My thesis focused on clustering and matching problems on graphs with efficient first-order methods.
