Academic Degree
Ph. D.
Field of Specialization
Chemistry in the Earth system
ORCID(Open Researcher and Contributor ID)
Total Priod of education and research career in the foreign country
Outline Activities
I am exploring chemically how the Earth was born, how it developed into its present state, and what it will be in the future. On the social learning, I am conducting activities to clarify ambiguous spatio-temporal scale of "environment".
Research Interests
  • Exploring the origin and ascending rate of mantle wedge carbon
    Identifying the source asteroid of the Earth
    Exploring factors improving learning motivation
    Development of teaching materials to experience the Earth

    keyword : Mantle, isotope, fluid inclusion, spectroscopy, teaching material, minute paper

Educational Activities
In order to increase the educational effect, it would be effective to stimulate the learning motivation of students. I am therefore investigating the class evaluation to identify the factors that can stimulate and improve students' learning motivation, and to explore the educational system that can continue the learning motivation even after the class period.
