Institute of Materials Structure Science, High Energy Accelerator Research Organization Research Assistant Professor
Motivation for Becoming a Researcher
I aspired to be a researcher because I wanted to develop systems and discover new phenomena. I hope to discover phenomena and materials that have some use to the world.
Your Greatest Strengths
I am skilled in growing atomically controlled ultra-thin films. I also construct computational models.
What Makes Your Research Interesting or Worthwhile
I feel that my research becomes interesting when I get completely different results from my initial expectations.
Other Research That Interests You
Recently, it has become possible to form two-dimensional electronic states on various oxides. Unusual physical properties may occur in two-dimensional metallic states. Thus, I would like to conduct research on forming and controlling such low-dimensional metallic states on oxides in order to develop new functional materials.
Interests Other Than Research You Would Like to Pursue
When I was a college student, I worked part-time at a coffee shop. I was so fond of coffee that I earned a black apron bestowed on only one person in the district. Given the opportunity, I would like to serve delicious coffee at a small research meeting.

Research Assistant Professor
Principal Work History:
In March 2015, I received a doctorate in research on “Electronic Structures and Carrier Dynamics at Metal Oxide Surfaces” from the Department of Physics under the School of Science at the University of Tokyo. From April 2015, I worked as a postdoctoral fellow at the Institute of Materials Structure Science of the High Energy Accelerator Research Organization and have worked in my current position since September 2017. My research is focused on growing oxide thin films and elucidating electronic states by in situ ARPES using synchrotron radiation.
