Research History

For a purpose of opening a new field of gravitational-wave astrophysics, I have been working on development of gravitational-wave detectors.

In ground-based detectors, I was working on design, development, and construction of TAMA300, which is placed in the campus of National Astronomical Observatory Japan (NAOJ). TAMA300 is an interferometric gravitational-wave detector with a baseline length of 300m. I also worked for the observation with TAMA300 and for search of gravitational-wave signals in collected data. I am working on LCGT, which is the future large-scale antenna planned to be built in Kamioka underground site.

As for space missions, I am working for DECIGO, a space interferometric antenna proposed in Japan. DECIGO has a roadmap to launch two milestone missions before its launch in 2027. I has been in charge of the first milestone satellite mission, DPF (DECIGO Pathfinder). As steps for DPF, I have promoted a tiny space mission named SWIM, and joined to microgravity experiments using a high-altitude balloon and an airplane parabolic flights for its tests. SWIM has been launched in 2009, and have been working fine over for a year.

Research Plan at GCOE

The purpose of my research in GCOE is to obtain prospects on gravity, and thus, on the nature of space-time. I am developing an instruments to measure the strength of gravity directly in shorter range than 1mm. With it, I am planning to test the inverse-square law of gravity, which is predicted to be broken in recent theories related with extra-dimensions.
