Interests:
My interests lie in the fields of Algebraic Geometry, Algebraic K-theory and Arithmetic Geometry. Currently, I am thinking about the geometries of schemes over valuation rings.My MR Author ID is 1551361. Here is my arXiv link.
Preprints
-
Gersten's Injectivity for Smooth Algebras over Valuation Rings, submitted, arXiv.
We prove that the K-groups of smooth algebras over valuation rings inject inside the same of their fraction fields.
- Purity over Valuation Rings, in preparation.
Publications
-
Tilting correspondences of perfectoid rings, J. Ramanujan Math. Soc. 38, No. 1 (2023) 23–32, journal.
We algebraically establish tilting equivalences of étale cohomologies of perfectoid rings taking values in commutative, finite étale group schemes without using tools from almost ring theory or adic spaces.
Below, I list some of the seminars that I am/was co-organising.

Other activities

From January 2021 to August 2023, I was in charge of building the website of
- École Parisienne d'Arithmétique et de Géométrie (EPAG).
The goal is to centralise all relevant informations for PhD students in number theory and algebraic geometry in the Paris region. -
In the year 2020-2021, I was a grader of
- Marathon d'Orsay de Mathématiques
