電気通信大学 大学院情報理工学研究科 機械知能システム学専攻 助教 Assistant Professor, Department of Mechanical and Intelligent Systems Engineering, Graduate School of Informatics and Engineering, The University of Electro-Communications
In March 2015, he completed his Ph.D. in Engineering [Hakushi (Kogaku)] at the Department of Systems Innovation, Graduate School of Engineering, The University of Tokyo. After the completion, he worked as a non-tenured assistant professor at the Department of Mechanical Engineering, Faculty of Science and Technology, Tokyo University of Science. Since October 2019, he has been a tenure-track assistant professor at the Department of Mechanical and Intelligent Systems Engineering, Graduate School of Informatics and Engineering, The University of Electro-Communications. His research interests include computational methods in solid mechanics, especially those on nonlinear deformation, cracks, and parallel computing.
