I am a theoretical physicist, who is interested in high-energy physics that goes beyond the StandardModel of elementary particles and fields. More precisely, I have been studying new physicsthat violates parity symmetry, such as the physics of axion-like particles. My research interestsare divided broadly into two areas: (i) the generation mechanism of chiral gravitational wavesin the early universe, and (ii) photon's birefringence effect due to the axion in thelate universe. I have developed novel ideas for detecting these parity-violating signatures withongoing/upcoming observations such as the cosmic microwave background (CMB), gravitational-wave detectors, and the resonant cavity experiments for the axion dark matter.
