I have been working on stellar structure and evolution. Stellar oscillations
provide us powerful tools to determine stellar parameters accurately, detect
stellar interiors and test internal physical processes. Space missions, such
as CoRoT and Kepler, have released continuous and high-precision photometric data, which are quite suitable for asteroseismic
analysis. Spectroscopic observations such as Lamost provide the values of
metallicity, effective temperature and gravity for millions of stars. Sets
of photometric and spectroscopic data are available on stars, which makes
it feasible to carry researches about stellar populations synthesis.
