Fabian Gloeckle Portrait

I am a machine learning researcher and mathematician working on language models for code and math. I am completing my PhD at Meta FAIR Paris and Institut Polytechnique de Paris, advised by Amaury Hayat and Gabriel Synnaeve.

My research focuses on improving language model reasoning through better pretraining (multi-token prediction), explorative and hierarchical reinforcement learning, and inference scaling. I also have a strong interest in formal mathematics in systems such as Lean. To advance automated scientific research, we must build highly parallel AI systems that interact with verifiers, self-verify, and conduct open-ended exploration.
