1982 graduated from the Physics Department of East China Normal University with a bachelor's degree. 1985 Master of Shanghai Institute of Optics and Mechanics. In 2000, he received his Ph.D. from the Department of Physics, State University of New York at Stony Brook. 1997 was promoted to associate researcher of Shanghai Institute of Optics and Mechanics. In 2005, he was selected into the "Hundred Talents Program" of Chinese Academy of Sciences. Now he is the director, researcher and doctoral supervisor of the Key Laboratory of Quantum Optics, Shanghai Institute of Optics and Mechanics, China Academy of Sciences, engaged in the research of cold atomic physics, quantum frequency standard and quantum information.

Liu Liang has been engaged in experimental research on cold atomic physics for a long time. Liu Liang has made outstanding contributions to the theory and experiment of "statistical verification of squeezed Poisson photons". The research achievement won the third prize of National Natural Science and the second prize of Scientific and Technological Progress Award of Chinese Academy of Sciences, and was one of the main winners. The theoretical explanation of the working mechanism below the Doppler cooling limit in the blue shift standing wave field has been solved. Liu Liang studied laser physics in Germany twice as a visiting scholar. In cooperation with Professor H. Metcalf, an internationally renowned scientist, the "dark state" laser cooling mechanism has been studied, and rich results have been achieved. His achievements make people realize a new cooling mechanism of sub-photon momentum, which is particularly important for the study of ultra-cold atomic physics. Liu Liang is a senior researcher at GATS, a space technology contract company of NASA, and is responsible for many research projects. He has presided over the research of infrared Fourier interferometer, atmospheric spectrum tester and far infrared atmospheric spectrum technology.
