I am currently

• an assistant professor at ZEN university (Japan) since April 2026 (New!),

• a tutor at Math space topos since July 2020,

• the founder and  one of the organizers of Categories in Tokyo since 2024, and

• an advisor to 角川ドワンゴ学園 研究部 since June 2025.

• a research associate at the Centre for Topos Theory and its Applications from 1st April 2025 to 31st March 2026, 

• a Ph.D. student at the University of Tokyo from April 2024 to March 2026, 

• a member of the research project Exploration of the Applicability of Combinatorial Game Theory (組合せゲーム理論の応用可能性の探求) from April 2025 to March 2026, 

• a FoPM student from April 2022 to March 2026,

• financially supported by DC1 from April 2024 to March 2026,

• a visitor at the Centre for Topos Theory and its Applications from 11 April to 26 June 2025,

• a member of AFSA project and a research assistant at the National Institute of Informatics from July 2022 to March 2025, 

• a master's student at the University of Tokyo from April 2022 to March 2024, and

• an undergraduate at the University of Tokyo from April 2018 to March 2022.

Interest

• Category theory and related (various) topics!

• Recently, I have been interested in how topos theory facilitates the exchange of ideas and intuitions between algebra, geometry, logic, computation, and combinatorics.

• I am also interested in coalgebras, (pro)finite combinatorics, combinatorial game theory, semiring theory, algebraic language theory, and pure category theory.
