Term: Apr. 2010 ～ Mar. 2015

Research Interests: Mathematics, Number Theory

Research Topic: The study of deformations of Galois representations and the special values of automorphic L-functions using Iwasawa theory

Masataka was born in Kesennuma-Oshima in 1980. As Oshima is an island, he went to high school by ship. From 1998 to 2007, he studied mathematics at Tohoku University, and received his Ph.D. in 2007. As a Ph.D. student, he visited the University of Wisconsin and Caltech. This experience that had a profound effect on his current research, which considers the study of properties of L-functions, which are very important functions in number theory. In particular, he is interested in the relation between the analytic information of L-functions at integer points and related arithmetic information. This problem relates to some famous conjectures, such as BSD conjecture and Langlands conjecture. He will try to solve this problem by using Iwasawa theory and Hida theory, two theories developed by Japanese mathematicians.
