Hi, I'm Kilian 👋

I'm an AI Research Scientist at Meta Superintelligence Labs.

Previously I was at Princeton University, researching agentic AI for software engineering and graph neural networks for high energy physics experiments.

Apart from that, I'm enthusiastic about open-source projects, learning Japanese, traveling, and photography.
