In recent years, I have been engaged in studying environmental isotope geochemistry, in particular in studying multiple isotopes, such as oxygen, sulfur, Boron and chlorine isotope of water samples for tracing their source and migration processes. The research results have been published in some international journals, such as Applied Geochemistry and Environmental Sciences & Technology. In the last ten years, I went to Toyama University, University of Waterloo, and University of Münster to learn analytical methods for measuring inorganic chlorine and sulfur(oxygen) isotope compositions, and hope to continue my research on these isotopic geochemistry of large river in China.

My research mainly focuses on environmental geochemistry of carbon, sulfur and chlorine in watersheds, with a main purpose to understand the linkages between the biogeochemical cycling of the elements and eco-environmental change. My recent research especially involves the variations in isotopic composition of chlorine and sulfur in both inorganic and organic matter and their application to tracing sources of various types of chlorine and sulfur in nature environments, including in water, air, soil and plants.
