My research focuses on trace metal cycling, accumulation and trophic transfer in food webs. There is a specific interest in mercury (Hg) bio-environmental contamination pathways in different ecosystems. In my research, Hg speciation and isotopic composition are determined in various bio-tissues and geochemical materials (e.g., rice, fish, soil, sediments and water sample etc.) to estimate Hg contamination extent from its polluted site to the target living organisms as well as the potential Hg biogeochemical pathways before its introducing into the food web. Moreover, my research makes a bridge between the biogeochemistry and ecotoxicology of Hg by combining tools of genes, histology and isotopes to understand Hg metabolic pathways and induced toxicological response. In the future, I would like to expend my work to the topics of Hg cycling changing in response to climate change in global scale and in specific places.
