Research Interest:

Big-Bang Cosmology and Element Genesis 


We study the evolution of the Universe, galaxies and stars and the origin of elementary particles and nuclei as observational probe of cosmic evolution.  The research subjects include big-bang cosmology, cosmic phase transition and the creation of particles and nuclei, origin of dark matter and dark energy and their roles in cosmic structure formation and the CMB anisotropies, explosion mechanism of supernovae and gamma-ray bursts and nucleosynthesis of heavy elements, neutrino astrophysics and cosmology, etc.  The ultimate goal is to construct a unified picture of space, time and the matter.
