Research

I am currently an assistant professor at the Global Scientific Information and Computing Center (GSIC), Tokyo Institute of Technology (Tokyo Tech). I am a member of the Aoki lab in GSIC. My primary research interests are general-purpose computing on graphics processing units (GPGPU), computational fluid dynamics, and high performance computing (HPC). Our group was awarded the 2011 Gordon Bell Prize Special Achievements in Scalability and Time-to-Solution for peta-scale phase-field simulations.

I received Ph.D. in Energy Science from Tokyo Tech in 2012. I graduated with M.S. in Physics from Tokyo Tech in 2007.
