About me

I am a Ph.D. student in mathematics at University of Münster, Germany. My supervisor is Prof. Ralf Schindler. I am from Japan. I am interested in mathematical logic, especially set theory, in particular, descriptive set theory and inner model theory.

I play Go and Chess. I have been playing Go since I was a child and I just started playing Chess recently.
