Welcome to my homepage!

I'm Keita Goto, a postdoc at RIKEN iTHEMS, where I have been working as a Special Postdoctoral Researcher since March 2026.

June 15th--17th: Participation in "Singular, tropical and non-archimedean interactions", Lille

August 24th-28th: Invited speaker at "勉強会：代数多様体の有理性と量子コホモロジー", Hokkaido. (All talks will be given in Japanese)
