I am primarily interested in theoretical astrophysics and cosmology, focusing on large-scale structure, cosmic microwave background, and inflationary models. My research aims at exploring the dark sector of the Universe and understanding the physical mechanism of perturbation generation in the early Universe. To explore the nature of dark energy, numerous large-scale galaxy surveys are ongoing or planned to be operational in a near future. These surveys will measure the positions and the shapes of millions of galaxies in the Universe with tremendous statistical power. However, precision measurements in these future surveys simultaneously bring in new challenges, demanding substantial advances in theoretical modeling and observational methods.
