I am a postdoc (wissenschaftlicher Mitarbeiter) at the University of Heidelberg in the group of Alexander Schmidt. I am part of the project C01 (Tame cohomology of schemes and adic spaces) of the SFB-TRR GAUS. My research focusses on studying rational points with the Chabauty–Kim method. Other research interests include the arithmetic of abelian varieties, especially the theory of complex multiplication, Shimura varieties, and related topics.

Until 2019, I did my PhD under the supervision of Tony Scholl at the University of Cambridge. In my thesis I studied extra “plectic” Galois actions on Hilbert modular varieties.

Before that I completed my studies at the University of Heidelberg (MSc), the University of Cambridge (MAST) and the Karlsruhe Institute of Technology (BSc).

Here is my CV

*Bounds on the Chabauty–Kim locus of hyperbolic curves*(with L.A. Betts and D. Corwin), Int. Math. Res. Not. IMRN, 2024. https://doi.org/10.1093/imrn/rnae067 arXiv.*Linear and quadratic Chabauty for affine hyperbolic curves*(with M. Lüdtke and J.S. Müller), Int. Math. Res. Not. IMRN, 2023. https://doi.org/10.1093/imrn/rnad185, arXiv.*Plectic Galois action on CM points and connected components of Hilbert modular varieties*, Bull. Lond. Math. Soc., 54(6):2254–2277, 2022. http://doi.org/10.1112/blms.12692, arXiv.*Plectic arithmetic of Hilbert modular varieties*, PhD Thesis, University of Cambridge, version 04/2020.

This term (SS 2024), I am the teaching assistent for *Algebraic Number Theory II*.
As always, the material is on Mampf.

In the summer, Wasilij Barsukow and I are offering a course about the *magic of solving or insolubility of (algebraic, Diophantine, differential) equations* at the Deutsche Schülerakademie Torgelow for 11th and 12th grade students.

During my PhD I gave talks in several reading groups about number-theoretic topics. As a postdoc in Heidelberg, these are now called Oberseminare or GAUS AGs. Details can be found here.

Here you can find a list of talks I have given at research seminars and conferences:

*Complex Multiplication*, notes of an overview talk I gave as part of the GAUS AG on Rigid Meromorphic Cocycles, 27/10/2023.*The main theorems of complex multiplication*, Smith-Knight and Rayleigh Knight Prize Essay, University of Cambridge, 01/2017.*Galois characterization of local fields*, master thesis, University of Heidelberg, supervised by Alexander Schmidt, 09/2015; in German; English summary here.*The Tate-module and the Weil pairing of an elliptic curve*, seminar write-up, University of Heidelberg, supervised by Oliver Thomas and Kay Wingberg, 07/2015; in German; notes here. The rank calculation of the -module of isogenies between two elliptic curves (as presented in Silverman) contains a little gap – one needs to use a bit more about the finitely generated submodules. This is necessary since otherwise something like would have rank . Thanks to Lennart Gehrmann for pointing it out. The issue is solved here.*p-adic L-functions*, part III essay, University of Cambridge, supervised by Tony Scholl, 05/2014.*Minkowski’s existence and uniqueness theorem for surface area measures*, bachelor thesis, University of Karlsruhe, supervised by Daniel Hug, 07/2012.
