Outline Activities
My research field is number theory. My recent subjects of study are multiple zeta values and related functions, finite multiple zeta values, and the behavior at real quadratics of the elliptic modular function.

I am supervising master and doctoral students based on these studies.

I am a member of the committee of algebra section of the mathematical society of Japan.

I am the editor-in-chief of the Kyushu Journal of Mathematics, and an editor of three other international mathematical journals.

Masanobu Kaneko, Shuji Yamamoto, A new integral–series identity of multiple zeta values and regularizations, Selecta Mathematica, New Series, 10.1007/s00029-018-0400-8, 24, 3, 2499-2521, 2018.07, We present a new “integral = series” type identity of multiple zeta values, and show that this is equivalent in a suitable sense to the fundamental theorem of regularization. We conjecture that this identity is enough to describe all linear relations of multiple zeta values over Q. We also establish the regularization theorem for multiple zeta-star values, which too is equivalent to our new identity. A connection to Kawashima’s relation is discussed as well..

Educational Activities
I am supervising several master and doctoral students. The goal is to make them write up their own research papers as master or doctoral theses.
Sometimes I give lectures at other universities in number theory at various levels.
Professional and Outreach Activities
Voluntary lectures at several high schools in Fukuoka, Saga, and Nagasaki..
