Who am I ?
I am a researcher at IBM Resarch, Tokyo. My research field is programming languages: one of the oldest research fields in computer science, and many interesting ideas are developed in their long history of study. Now, what remains to be done is to close the gap between ideas and practices there, and this is my recent research goal.
