 Biography

I received B.S. and M.S. degree in Communication Engineering from University of Electro-Communications in 1987 and 1989, respectively and the Ph.D. degree in Mathematical Sciences from University of Tokyo in 2000. Since, 1989, I have been with IBM Research - Tokyo. My research interests include speech processing, content security and multi-core software.
