Hi, I’m Tom.

I'm a PhD researcher in machine learning at the University of Freiburg and the ELLIS Institute Tübingen. This is my corner of the web: a short CV and an occasional blog.

About

I work on prompt optimization and multi-agent system optimization in Frank Hutter's group — working toward the automated design and optimization of multi-agent systems. Before the PhD I was a data scientist at Airbus and studied statistics and data science at LMU Munich. I build in the open — my code, papers, and benchmarks are public.

I have opinions about what the future of agentic systems should look like — and mathematical and statistical evidence to back them up. I write about both on the blog.

The best way to reach me is by email: [email protected] — or find me on GitHub, Google Scholar, LinkedIn, YouTube.
