Hi, I’m Tim!
I’m currently a substitute professor at the Technical University of Munich. I am a member of the COST Action InterCoML and the Munich Center for Machine Learning.
My research lies at the intersection of mathematical analysis, optimization, and machine learning. I work on consensus-based optimization methods, robustness and stability of neural networks, and learning problems in imaging and inverse problems.

Allure of Craquelure: A Variational-Generative Approach to Crack Detection in Paintings
Together with Laura Paul, Holger Rauhut, Martin Burger and Samira Kabri we posted a new preprint on Allure of Craquelure: A Variational-Generative Approach to Crack Detection in Paintings.
Bridging AI and Theory: Workshop on the Mathematics of Transformers at DESY
At a recent workshop hosted by DESY, around 30 experts from across Europe came together to explore the theoretical foundations of transformers, the core architecture behind modern large language models. Organized by researchers from DESY, Helmholtz Imaging,...
Position-Blind Ptychography: Viability of image reconstruction via data-driven variational inference
We put a preprint on the arXiv dealing with position-blind pytychography. Compared to the standard setup, here we ask ourselves how well the reconstruction problem can be solved, when the scan position are completely unknown. Furthermore, we explore how to ...
Adversarial flows: A gradient flow characterization of adversarial attacks
I’m happy to share that our paper Adversarial flows: A gradient flow characterization of adversarial attacks has been published in the European Journal of Applied Mathematics.
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...

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.
