My research interest is mainly in the theoretical modeling of observational cosmology. My past research covers the modeling of correlators such as galaxy bispectrum and void-galaxy correlation with the effect of redshift-space distortions as methods to test cosmological models and the property of gravity.

We are at the dawn of illuminating the property and nature of dark energy and other intriguing mysteries of cosmology by current and next-generation cosmological surveys. Recently, I am interested in the phenomenological dark energy model based on axion-like particles slightly breaking the cosmological principle of isotropy and homogeneity, whose possibility is implicated by recent observations.
