Biography

I am a post-doctoral researcher at the AI Lab of Vrije Universiteit Brussel (VUB). My research focuses on reinforcement learning (RL) and representation learning in RL. Specifically, I work on methods for delivering reliable and adaptive learning agents, especially by combining RL with world models. I am also interested in formal verification, abstraction, and synthesis as tools for building AI mechanisms that can justify and certify the behavior they adopt. I am also teaching the course Theory of Computation at the VUB.

Before, I did a joint PhD within the VUB and the University of Antwerp under the supervision of Ann Nowé and Guillermo A. Pérez. My thesis focused on enabling the formal verification of deep RL policies (you can find the dissertation here).

My curriculum vitae is available here.
