Recently, the field of particle cosmology experienced an extraordinary development. The observations of type Ia supernova, the large-scale structure, and the cosmic microwave background have placed tight constraints on the standard cosmological model. Now it is widely believed that a breakthrough of the relevant theories will come from the intersection between cosmology and particle physics and that it may lead to a revolution in our understanding of fundamental physics. My research aims to understand the inflationary cosmology and the physics of the early universe relevant to inflation, and the theory of dark energy.

My research interests involves the following fields:
1. Heavy flavor physics & CP violation: The CP violation of the fundamental interactions is one of the necessary conditions for the existence of our universe. The heavy flavor physics is one of main fields to probe the origin of the CP violation in the Standard Model of particle physics and its possible extensions.

2. QCD factorization and effective field theories: The quantum chromodynamics (QCD) is a well-established theory for the strong interactions. The most important properties of QCD — the asymptotic freedom and color confinement, makes a typical high-energy processes involving strong interactions generally entangled with perturbative and non-perturbative contributions. To disentangle the perturbative contributions from the non-perturbative ones, the QCD factorization must hold. Recently, the effective field theory has been becoming one of the most powerful tools in proving the QCD factorization and perturbative calculations.

3. Quarkonium physics: The study on productions and decays of the quarkonium improves our understanding in the properties of QCD in non-relativistic bound-state system of heavy-quark and anti-heavy quark.

4. Origins of masses and mixings of fermions in the Standard Model and its extensions. In the SM and its various extensions, the origin of masses and mixings of fermions is due to the Yukawa couplings which are not well-constrained. Thus the masses and mixings of fermions become the main sources of the free parameters in the SM and its extensions. The so-called horizontal symmetry and its breaking is one of the most popular way to study the patterns of masses and mixings of fermions observed in reality.

The prime goal of LHC and ILC is to discover and to perform a pricision measurement on the TeV structure of the nature, respectively. The running of LHC and its data collection and analysis as well have further prompted the researches on TeV theories and the relevant phenomenological studies. Therefore to study the phenomenologies of various new models of TeV is meansingful, while to study how to test these models at LHC and ILC is practical and useful. I focuses on the study of the electroweak symmetry breaking mechanism and the mass origin at LHC, and plans to study at both LHC and ILC on 1) properties and detection methods of Higgs bosons for varies TeV models,2) the detection of dark matter particles, 3) the detection of other new particles, like new vector bosons, new colored fermion, and so on. I hope that my research can promote and deepen our understanding on the TeV structure of nature.

My research interests are theoretical nuclear physics and quantum many-body problems. I have been mainly engaged in three research directions, namely, (1) reaction mechanism of exotic nuclei and synthesis mechanism of superheavy elements, (2) theoretical studies of exotic nuclear structure and astrophysical related nuclear structure, (3) many-body theory and relevant numerical simulation.
