Associate Professor at University of Ljubljana

Research

My current research focuses on computational statistics, machine learning, and natural language processing. My goal is to advance computational scientific discovery by developing methods that help uncover the hidden logic within vast amounts of human knowledge and data. Specifically, I focus on:

  1. Mechanisms of recombinant knowledge innovations: How can we open the black box of large-language models to uncover their internal mechanisms, especially those enabling complex reasoning?
  2. Trustworthy scientific discovery methods and tools: How can insights from mechanistic understanding be transformed into practice for building LLMs that are reliable, truthful, and safe in real-world applications?
