I am a Research Scientist at Google DeepMind currently working on developing better algorithms for large language model post-training. Prior to that, I obtained my PhD from the Department of Computer Science of ETH Zürich, working under the supervision of Fanny Yang in the Statistical Machine Learning group. Before that I completed a MSc degree in Computer Science at ETH Zürich and a BSc degree in Computer Engineering at Politehnica University Bucharest.

I’m broadly interested in various theoretical and methodological aspects of trustworthy ML (distribution shifts, fairness, uncertainty estimation), data-efficient learning (active learning, semi-supervised learning) and representation learning.
