I am a research assistant in the Individual and Collective Reasoning (ICR) group at the Computer Science Department of the University of Luxembourg. I took the PhD degree from the University of Aix-Marseille I, France. After that, I worked as a research associate at the Department of Computer Science of the King's College London, UK, and subsequently moved to Luxembourg.
I am a co-editor of the Handbook of Deontic Logic and Normative Systems. I was the general conference chair of RuleML+RR 2018 and a PC co-chair of DEON 2014.
