I am a Master's student in Advanced Computer Science at the University of Oxford, co-advised by Prof. Michael Bronstein (Oxford) and Prof. Jure Leskovec (Stanford). I was a Visiting Researcher at Stanford University and continue to collaborate with the Leskovec group. I am an ASEF Junior Research Fellow. Previously, I completed a BSc in Mathematics and Computer Science at the University of Ljubljana and spent a fruitful year doing research in the industry at Teads, pushing the frontier of real-time bidding and large-scale recommender systems.

My research interests span the theoretical and applied foundations of machine learning, with a focus on developing principled and scalable algorithms for learning on structured data and graph neural networks. I am also exploring the design of foundation models for relational domains.

🏀 Interesting fact: I played basketball professionally and was the youngest player in the highest national league and in international competitions.
