I am computer scientist working on Explainable AI. My research focuses on counterfactual explanations, with special emphasis on their robustness. I am affiliated with the Centre for Explainable AI at Imperial College, where I am supported by an Imperial College Research Fellowship.

Before, I was research associate in the Verification of Autonomous Systems group at Imperial College. I obtained a PhD in Computer Science from RWTH Aachen University and UNIGE with a thesis on AI Planning.
