Hi, I'm Kohki!

I am a PhD student in mathematics at the University of Tokyo. My supervisor is Yoshikata Kida. 

My main interest is measured group theory, particularly:

・Probability on groups/homogeneous spaces

・Orbit equivalence theory

・Graph limits

Research

In February 2026, I will be visiting University of Warwick, hosted by Oleg Pikhurko. I hope to see many of you there! 

Here is my CV.
