Academic Background
Jian holds a Ph.D. degree in soil science from the Swedish University of Agricultural Sciences. Before joining GIWS, he conducted post-doctoral research at the Chinese Academy of Agricultural Sciences, the Pennsylvania State University and U.S. Department of Agriculture — Agricultural Research Service. He currently serves as an Associate Editor for the Journal of Environmental Quality and Is leading in organizing a special issue on Agricultural Water Quality under Cold Conditions.
Research Interests and Expertise
Jian is a soil scientist with a research focus on agricultural nutrient and water quality management. His research involves evaluating impacts of climate and agricultural management practices on nutrient cycling and water quality at the field and watershed scales, using both experimental and modelling approaches. Jian's research contributes to improving the understanding of nutrient cycling and transport in the agricultural sector and designing beneficial management practice to minimize nutrient losses from land to water. The work will help to address one of the Institute's main research areas - water quality, towards sustainable water resource management.
