He graduated from Sichuan Agric. Univ., P.R. China with B. Agronomy in 1983, and from Northwest Institute of Soil and Water Conservation, CAS with M.S. in Soil Chemistry & Plant Nutrition in 1988, and from Nanjing Institute of Soil Science, CAS with Ph. D. in Soil Chemistry in 1991. He was a Post- Doctoral Research Fellow at the State Key Laboratory of Environmental Geochemistry, Institute of Geochemistry, CAS from Sept. 1991 to April. 1994. He did collaborative research work in Monash University and the University of Western Australia in Australia, and in Drexel University and Massachussetts, USA, Tuebingen University, Germany, and Swiss Federal Institute of Aquatic Environmental Science and Technology (EAWAG). He was Associate Professor and then Professor at SKLOG of Guangzhou Institute of Geochemistry, CAS from December 1997. He is a Board Member, Society of Environmental Toxicology and Chemistry from 2007.

B.A: Sichuan Agric. Univ., P.R. China, 1983

M.S: Northwest Institute of Soil and Water Conservation, Chinese Academy of Sciences, 1988

His early research (1985-1992) focused on laboratory-scale experimental and theoretical investigations of environmental physicochemical processes of trace metals on the surfaces of organic matter, clay minerals, and soils.  His late work emphasized on biogeochemical processes governing the behavior of inorganic and organic contaminants in soils and freshwater.  His most recent research (1998-2008) has involved in distribution, transport, biodegradation, and bioavailability of organic contaminants in soils and sediments.
