Academic Degree
Doctor of Engineering
Field of Specialization
Geothermics (Geothermal Engineering)
Outline Activities
The main target of my research is "Utilization of geothermal energy". For this target, I research some geothermal field by mainly geophysical methods and evaluate the geothermal fluid flow of the field by some numerical model.
Now I am conducting three joint researches with other organizations. And I was a member of some committees of New Energy and Industrial Technology Development Organization (NEDO).
I have two lectures in English for foreign students.

Professional and Outreach Activities
I am conducting some joint researches with other organizations (see the list of "Joint research/surveys and research commissions"), and was a member of some committees of NEDO (see the list of "Committee activities").
JICA international training course "Intensive Training for Geothermal Resource Engineers" has been commenced in 2016 by Department of Earth Resources Engineering, Kyushu University, and I was a deputy course leader..
