The Language, Computation, and Cognition Lab (LaCoCo) https://lacoco-lab.github.io/home/ at Saarland Informatics Campus (Saarbrücken, Germany), directed by Michael Hahn https://mhahn.info/, invites applications for fully funded PhD and postdoc positions, with a flexible start date.
* **RESEARCH AREAS*
We’re especially excited about projects on:
* Architectural limitations of large language models (LLMs), especially from theoretical perspectives * New architectures and efficient reasoning for LLMs * Mechanistic interpretability * Theoretical foundations for AI safety
* * You’ll have substantial freedom to shape your topic within the lab’s scope.
* * *ABOUT THE LAB*
The lab is generously supported by an Emmy Noether grant (DFG) and has substantial GPU resources. We regularly publish at top venues (e.g., six NeurIPS/ICML/ICLR papers in 2024–2025; ACL Best Paper 2024) and are embedded in Saarland Informatics Campus (https://saarland-informatics-campus.de/en/), a world-class environment for computer science research.
