Professor Liu's main research interest is spectroscopic study of emission line nebulae, with an emphasis on the physical processes and radiative mechanisms governing photoionized gaseous nebulae. Studies of emission line nebulae yield information of stellar nucleosynthesis and the enrichment of the interstellar medium, and of the chemical evolution of galaxies. Currently, Prof. Liu is leading a large spectroscopic survey towards the Galactic anticenter with the newly built Chinese Large
