Hello world!
I am an experimental astrophysicist with the main focuse set on gravitational wave searches and precision laser interferometry. My ultimate goal is to directly probe the very early Universe by observing primordial gravitational-wave backgrounds. I am currently an associate professor in the Space Astronomy and Astrophysics Department of ISAS, working for LISA, KAGRA and SILVIA by conduting a number of laboratory-scale experiemnts.
If you are interested in joining our group at ISAS in JAXA, please feel free to contact me.
Hobbies: reading, bonfiring, guitar (electric and acoustic) , studying Yokai

Classical and Quantum Gravity, 42(10) 105007-105007, May 14, 2025 Peer-reviewedAbstract Future gravitational wave observation in space will demand improvement in the sensitivity of the local sensor for the drag-free control. This paper presents the proposal, design, and demonstration of a new laser interferometric sensor named Quadrature Interferometric Metrology of Translation and Tilt (QUIMETT) for the drag-free local sensor. QUIMETT enables simultaneous measurements of both translational displacement and tilts of a reflective object with a single interferometer package. QUIMETT offers a characteristic feature where the sensitivity to tilt is independent of the interference condition while maintaining the ability to measure the translational displacement for a range greater than the laser wavelength. The tilt-sensing function has been demonstrated in a prototype experiment. The tilt sensitivity remained unchanged in different interference conditions and stayed at 10 nrad Hz at 0.1 Hz.
