Research Activities

My research field is arithmetic geometry. I mainly work in Hodge theory, algebraic K-theory, higher Chow group, mixed motives and regulator.

The classical theory of regulator goes to Dirichlet in the 19th century who showed that it is described by the special values of L-functions.
In 1980’s Beilinson gave a vast generalization of Dirichlet’s theorem.
However still it is a widely open question. I study Beilinson’s regulator or its p-adic counterpart using Hodge theory, p-adic Hodge theory and so on.
