About me

I am a researcher in the Systems group at IBM Research - Tokyo in Japan, which is part of IBM's Research Division. I joined the laboratory in 1992. I was on assignment at the IBM T. J. Watson Research Center from 2008 to 2009.

My research interests are in optimizing compilers, language runtime, parallel processing, and processor architectures.

I was involved with the High Performance Fortran (HPF) compiler from 1992 to 1995. I was involved with the Java Just-In-Time compiler from 1996 to 2003, which is included in the IBM Developer Kit, Java™ Technology Edition. I was involved with end-to-end performance improvement of Java 2 Enterprise Edition (J2EE) application such as SPECjAppServer2004 from 2004 to 2005. I was involved with investigation of the performance impact of Java applications on multi-core systems from 2008 to 2009. I was involved with dynamic compilation techniques for dynamically typed languages from 2010 to 2011. I worked for compilation and runtime techniques for exploiting new hardware features on s390 architecture from 2012 to 2013. Recently, my research focuses on compliation and optimizations from Java to GPGPU.


I received an M.S. (1992) and Ph.D. (2002) from Waseda University, in the field of information and computer science.
I am a member of ACM (Senior Member), IPSJ, and JSSST.
