Interests:
My interests lie in the fields of Algebraic Geometry and Arithmetic Geometry. Currently, I am thinking about torsors under reductive group schemes on smooth algebras over valuation rings.
Here is my arXiv link.
(Pre)Publications

Tilting Correspondences of Perfectoid Rings, October 2021, accepted to the Journal of the Ramanujan Mathematical Society
We present an alternate proof of a vanishing result of étale cohomology on perfectoid rings due to Česnavičius.

GrothendieckSerre over Smooth over Valuation Rings, in preparation.
We show that a generically trivial torsor under a reductive group on a smooth algebra over a valuation ring of rank 1 is trivial.

Purity over Valuation Rings, in preparation.
Below, I list some of the seminars that I am/was coorganising.

Other activities

Since January 2021, I am 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.
 I am a volunteer for the
 "Accueil International EGMathPS".
Our objective is to help international students better integrate to ParisSaclay and France in the context of their studies in mathematics (Master and PhD). So, if you are a Math student in Orsay/IHES/Evry/Versailles/Ecole Polytéchnique/ENS ParisSaclay and you would like to join our discord channel, feel free to send me an email!

In the year 20202021, I was a grader of

Marathon d'Orsay de Mathématiques
