I am a postdoctoral fellow based at the Institut für Algebra, Zahlentheorie und Diskrete Mathematik, Leibniz Universität Hannover. I am primarily interested in arithmetic geometry, in particular, p-adic Hodge theory and p-adic cohomology theories.
Previously, I have been a Simons Collaboration postdoctoral fellow at IMJ-PRG, Sorbonne Université (2024-26), a JSPS postdoctoral fellow at The University of Tokyo (2022-24), and a postdoc at the Université de Lille (2022). Before that, I was a doctoral student at the Institut de Mathématiques de Bordeaux. Before joining the doctoral program, I was an ALGANT master student in Leiden and Bordeaux. Even before that, I was a software engineer.
