Introduction to Regularization and Learning Methods for Inverse Problems
Together with Danielle Bednarski we uploaded our lecture notes Introduction to Regularization and Learning Methods for Inverse Problems to arXiv. The notes are based on a course we taught at the University of Hamburg in the winter term 2024/2025.
Consensus-based optimization for closed-box adversarial attacks and a connection to evolution strategies
Together with Leon Bungert and Philipp Wacker we uploaded a paper to arXiv, which shows how CBO can be used to create closed-box adversarial attacks. Beyond that we establish an interesting connection between CBO and evolution strategies. The paper can be f...
Analysis of mean-field models arising from self-attention dynamics in transformer architectures with layer normalization
I’m happy to share that our paper Analysis of mean-field models arising from self-attention dynamics in transformer architectures with layer normalization has been published in the Philosophical Transactions of the Royal Society A.
Dr.-Klaus-Körper Prize
I am very happy to share that I was awarded the Dr.-Klaus-Körper Prize for my PhD thesis today. The prize is awarded by the GAMM at the annual meeting in Poznań.
MirrorCBO: A consensus-based optimization method in the spirit of mirror descent
Together with Leon Bungert, Franca Hoffmann and Doh Yeon Kim we poste a new preprint on MirrorCBO: A consensus-based optimization method in the spirit of mirror descent.
Analysis of mean-field models arising from self-attention dynamics in transformer architectures with layer normalization
Together with Martin Burger, Samira Kabri, Yury Korolev and Lukas Weigand we posted a new preprint called Analysis of mean-field models arising from self-attention dynamics in transformer architectures with layer normalization.

LaTeX Projects
During my time at university, LaTeX was constantly following me around and helping me out. I tried to make everything easier by producing some templates that can be reused by me and others for various projects.
Research
Here’s an overview of some of my research projects and interests.
Teaching
Here is an overview over teaching material that I published online.
