Jonas Hübotter Ph.D. Student jonas.huebotter@inf.ethz.ch OAT Y 17 Linkedln External Website My current research aims to leverage foundation models for solving hard tasks through specialization and reinforcement learning. Beyond this, I have broad interests including (approximate) probabilistic inference, optimization, and online learning. Publications 2025 Active Fine-Tuning of Multi-Task Policies M. Bagatella, J.
