Welcome! Since December 2024, I am a Postdoctoral fellow at the University of Duisburg-Essen in the research group of Massimo Bertolini.
From March 2024 to June 2024, I was an Invited Researcher at the I.H.E.S..
From March 2023 to February 2024, I was a Postdoctoral fellow at the University of Heidelberg in the research group of Otmar Venjakob.
From March 2022 to December 2022, I was a Postdoctoral fellow at the University of Bordeaux under the supervision of Denis Benois as part of the GALF project.
From March 2021 to February 2022, I was a Postdoctoral fellow at the Università degli Studi di Genova working with Stefano Vigni. I was supported by the INdAM and the research grant: assegni di collaborazione ad attività di ricerca « Ing. G. Schirillo ».
From August 2018 to December 2020, I was a Postdoctoral fellow at the Max Planck Institute for Mathematics. In Fall 2020, I was also a (remote) Postdoctoral participant of the program Cohomology in Arithmetic held at the Centre de Recherches Mathématiques in Montréal.
My Ph.D. advisor is Antonio Lei.
I am interested in number theory, especially in Iwasawa theory and p‑adic Hodge theory.
