I am a Senior Machine Learning Researcher at Merantix Momentum. My current research focuses on probability, information theory and compression, with applications to efficient and robust foundation models and to high-dimensional inference and hypothesis testing.
In recent years, I have worked on modeling problems across molecular dynamics, satellite imaging, forensic genetics, wireless communications, and thermodynamics—sometimes on the experimental side and sometimes in safety-critical production systems.
I received my PhD in Mathematics in 2022 under the supervision of Christof Schütte in the Biocomputing group at Freie Universität Berlin. In my dissertation, I investigated nonparametric models for Markov processes. During my PhD program, I spent some time doing R&D in the aircraft engine development division of Rolls-Royce Deutschland.
During my time as a postdoctoral researcher in the group of Claudia Schillings at Freie Universität Berlin, I worked on the mathematical theory of operator learning and conditional mean embeddings, developing statistical guarantees for the theoretical foundation of approaches in causal machine learning, reinforcement learning and uncertainty quantification.
