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.
