Molecular clouds and star formation in the Milky Way

Large-scale surveys in CO isotopic lines not only provide the information on the precise content and distribution of molecular gas in Milky Way, but also reveal the kinematics of molecular clouds. I was a member of the Milky Way Imaging Scroll Painting (MWISP) project. Since 2017, I become a member of the GLOSTAR (GLObal view of STAR formation) project.

Astrochemistry

As Sir Eddington said: "Atoms are physics but molecules are chemistry." Astrochemisty is a field that aims to study molecules in space. Spectral line surveys are the only way to obtain a complete unbiased view of the molecular inventory, establishing that spectral line surveys become one of the most important tools to study astrochemistry. I have been involved in many line survey projects.

Other interests

I am also interested in astronomical masers, molecular gas and dust in circumstellar envelopes of evolved stars and external galaxies. Radio and sub/millimeter observations can used to investigate these scientific topics. I am involved in the M2O team.
