Research

＊ Ongoing research topics in cosmology

I study cosmic inflation, dark matter and dark energy from both theoretical and observational approaches: model building, phenomenological forecasting, observational testing and analysis tool developing. I am also involved in some experimental studies on LiteBIRD, a JAXA-led international space mission to measure the cosmic microwave background (CMB), as a formal member.
Keywords:

• Cosmic neutrinos (masses, effective number, chemical potential)
• Statistics of cosmic observables (CMB anisotropies, CMB distortions, galaxies, 21-cm anisotropies, gravitational waves, ...)
• Inflationary models involving axions, gauge fields and higher spin fields
• Cosmic anomalies (anisotropy, inhomogeneity, parity violation, non-Gaussianity)
• Primordial gravitational waves / gravitons
• Dark matter search
• Data analysis and apparatus development in Planck and LiteBIRD
