I am interested in number theory, particularly Grothendieck’s theory of motives and Beilinson’s conjectures. During my Ph.D. work at the University of Tokyo under Kazuya Kato, I worked on Drinfeld modular analogue of Beilinson’s result on modular curves. In a joint work with Seidai Yasuda we generalized it to higher dimensions, and applied it to the computation of lower K-groups of elliptic curves over a function field of a curve over a finite field.
