Research Interests

    Precision spectroscopy methods and the precision spectroscopy of molecules: tests of the fundamental physics or chemistry with high accuracy, searching for new physics, determination of fundamental constants, and quantum metrology. The main research content currently underway:
    1.Precision spectroscopy of molecular hydrogen: testing quantum chemistry theory, determining proton / electron mass ratio and proton radius；
    2.Precision spectroscopy of polar molecules: testing varying constant；
    3.Development of techniques such as low-temperature collisions and molecular cooling in order to improve the precision of molecular spectroscopy measurement.
