Since September 2024, I am a PhD student in the working group of Stefan Schröer at the university of Düsseldorf. My second advisor is Kay Rülling at the university of Wuppertal. I am funded by the Research Training Group GRK2240: Algebro-Geometric Methods in Algebra, Arithmetic and Topology. From 2022 to 2024 I was a student of the ALGANT master program, spending my first year at the university of Leiden, and my second year at the university of Regensburg. In Regensburg I wrote a thesis titled "A local Version of Kashiwara's Conjecture" under the supervision of Moritz Kerz (linked below).
Broadly speaking, I am interested in algebraic geometry in positive and mixed characteristic.
My CV.
Below you will find some unpublished writing of mine that I think might be interesting for some people that come across it.
Abstract: We determine the Bloch-Kato ordinary (quasi-)bielliptic surfaces in every characteristic. We relate the notion of Bloch-Kato ordinarity to the notions of ordinary, classical and supersingular introduced for (quasi-)bielliptic surfaces by Ivo Kroon.
Abstract: We relate the étale fundamental group of a nodal curve to the étale fundamental group of its normalization. Combined with known results on étale fundamental groups of smooth curves in positive characteristic, this gives us a good grip on the fundamental groups of these nodal curves.
Abstract: We improve a classical spreading argument for l-adic representations allowing us to preserve the property of having finite determinant. Additionally, we prove that such spreadings are unique in an appropriate sense.
Abstract: We define the notion of a “base extension”, an abstract framework to axiomatize the notion of Galois descent in various contexts. We subsequently retrieve the well known principle that twisted forms of a k-object X are parametrized by the Galois cohomology set H1(k, Aut(Xs)) for practically all types of objects.
