Hi, my name is Tomasz Sternal. I am a PhD student in the Scalable Parallel Computing Lab at ETH Zurich, supervised by Torsten Hoefler. My research focuses on the interpretability and reasoning capabilities of transformer-based models.
Before starting my PhD, I worked for five years as a Technical Lead at Palantir Technologies.
News and Updates
- 20.05.2026 I will be presenting my LLM interpretability research at this year’s edition of Pint of Science Zurich
- 30.04.2026 Our work on Process Reward Agents (PRA) got accepted to ICML 2026 in Seoul!
