Master's student in Data Science & AI · SPAR Research Fellow
I’m a final-year Master’s student in Data Science and Artificial Intelligence at the University of Trieste, focused on deep learning and mech interp.
I want to understand how LLMs work internally and how we can use that knowledge to build better and safer systems for the future.
Recent work · SPAR fellow on Implicit Personalization — probing the internal user models LLMs build (persona vectors). See the project page for details.
In parallel: mechanistic interpretability of Mixture-of-Experts models (OLMoE, GPT-OSS) — adapting HeadPursuit / SOMP to expert specialization.
