Research Seminars
I'm co-organizing an international Zoom seminar for computability theorists: Computability Theory and Applications Online Seminar
I'm also co-organizing a local seminar with Prof. Matsubara and Prof. Yoshinobu: Nagoya Logic Seminar

- (2022) Analysis of Weak Negation Based on Modal Semantics
- (2020) Wadge-like Hierarchies under Determinacy Hypothesis
