About
I am a postdoctoral researcher at the Department of Computer Science of the University of Luxembourg, where I am a member of the CLAiM group on Computational Law and Machine Ethics led by Dr. Réka Markovich.
I am an AI researcher focusing on symbolic and hybrid approaches for human-level and human-centered AI in application areas like digital transformation of law and finance.

Teaching Profile and Activities
I enjoy both research-based teaching and foundational teaching. My research-based teaching focuses on advanced topics in knowledge representation and reasoning, including logic and formal argumentation in AI. Additionally, I contribute to foundational education by coordinating textbook drafting and teaching core subjects in computer science, such as discrete mathematics, propositional logic, and first-order logic.
