My research interest lies in the field of theoretical cosmology, especially for the origin of primordial density fluctuations in the inflationary period of the early universe, and the cosmic large scale structures which are formed as a result of amplification of the primordial density fluctuations due to gravitational instability.

I have studied the statistical feature of the primordial density fluctuations, and developed analytical models to describe the evolution of the cosmic structures. One goal of my research is to clarify the evolution of the cosmic structures through comparing my models with some of large galaxy surveys.
