1960 graduated from the Department of Physics of Donghai University with a bachelor's degree. 1968, master's degree and doctor's degree in physics from University of California, Berkeley. He has been a researcher at Princeton Institute of Advanced Studies for a long time from 197 1974, doing basic research on plasma physics and nuclear fusion theory, and making important contributions to the parametric instability and nonlinear theory of laser plasma interaction. Since 1975, he has worked in the University of Maryland for 27 years. 1975, the school hired him as a full professor of physics department to lead the plasma theory research group. 65438-0979 served as the director of the newly established plasma and nuclear fusion energy laboratory, leading the research of plasma physics. Later, he served as the president and vice president of the institute, the first Chinese vice president of the institute and the director of the Institute of Global Chinese Affairs. 1993 served as the president of the american physical society plasma branch, 1996- 1999 served as the chairman of the plasma physics committee of the National Research Council (NRC) of the American Academy of Sciences, and from 2000 to 2003, he served as the director of the physics and astronomy committee of the NRC, the authoritative organization for formulating policies and plans for physical astronomy in the United States. He was awarded the Outstanding International Service Award by the University of Maryland. He received an honorary doctorate from Chalmers Institute of Technology in Sweden for his achievements in plasma physics. In February 2003, Liu Quansheng was elected President of National Central University. Former presidents of Taiwan Province Central University include Dai Yungui, Yu Chuantao and Liu. After returning to the United States, Liu Quansheng also served as the dean of the Confucius Institute at the University of Maryland (the Confucius Institute at the University of Maryland is the first Confucius Institute in the world). For university education, Liu Quansheng advocates teaching students in accordance with their aptitude, giving full play to their personal advantages, teaching in the spirit of research, and making good use of new learning technologies such as computers and networks.
