Promoting international exchange through research collaborations.

About Research

In my role as visiting professor at Institute of Quantitative Biology I have two major goals. The first is to continuously develop the UTokyo-KI link program which promotes internationalization through research and educational exchange. The second is to collaborate with other principal investigators at the institute to reveal the role of a newly discovered interplay between DNA structure and chromosome dynamics during development and cellular growth.
