Research Area 
Algebra (Number theory, Iwasawa theory, elliptic curves, Selmer groups, padic Lie extensions) 
Research Institute Theme 
It is believed that there exist mysterious relations between two quite differnt invariants, Selmer groups and Lfunctions, which are both attached to algebraic number fields or elliptic curves. Iwasawa theory studies generalizations and "padic" refinements of these relationships by considering these invariants over some big Galois extensions. Currently, I am studying "Noncommutative Iwasawa theory" and "Iwasawa theory for Galois representations" which are attempts to generalize the classical framework of Iwasawa theory.
