Hi! I'm Moritz.
I'm a PhD student at the AIML Lab at TU Darmstadt
building AI models that can truly reason causally.

Find out more about my research below.

About Me

I'm a fourth year PhD student at the AIML Lab at TU Darmstadt, Germany, working together with Kristian Kersting and Devendra Singh Dhami, trying to understand how causal reasoning can be integrated and learned by modern LLM and similar AI systems. I'm furthermore interested in how causal systems evolve and change. In my recent work I formalized meta-causal models which are able to model the dynamic emergence and vanishment of qualitative causal relations under the assumption of an underlying mediation process.

If you find any of my works intersting or would like to collaborate, feel free to reach out to me!
