I am currently

• a Ph.D. student at the University of Tokyo,

• a FoPM student since April 2022,

• financially supported by DC1 since April 2024,

• a tutor at Math space topos since July 2020,

• a (unique) organizer of Categories in Tokyo, 

• a research associate at Centre for Topos Theory and its Applications since 1st April 2025 until 31st 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, and

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

and, I was

• a bachelor and master student at the University of Tokyo,

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

• a visitor at Centre for Topos Theory and its Applications since 11 April until 26 June 2025.

Interest

• category theory and related (various) topics!

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

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