I am a researcher affiliated with the Centre for Explainable AI at Imperial College. My research largely focuses on safe & explainable AI, with special emphasis on contrastive explanations and their robustness. My work is currently 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.
