ADMINISTRATIVE DUTIES.

From February 2021 to March 2022, I was a member of the Institut Fourier research council (UMR 5582, non-permanents).

In 2020-2021, I was co-organizing the PhD students' seminar, "Séminaire compréhensible".


OTHER DOCUMENTS.

Ph.D thesis defense slides: slides.
Ph.D thesis: pdf. The first two chapters are a self-contained introduction to non-Archimedean geometry, starting from scratch. The first chapter in particular, which treats the algebraic preliminaries, has been deliberately written in such a way that it should be readable to a(n interested) Master's student.
