Research interests
My research primarily focuses on the intersection of deep-sea geochemistry and geomicrobiology. Recently, I have concentrated my interests on the biogeochemical cycling of key elements in deep-sea extreme environments, such as seafloor cold seeps, hydrothermal systems, and oceanic plate subduction zones.

Research interests
My research mainly focuses on the geochemistry and genesis of volcanic rocks from different tectonic settings, including mid-ocean ridges, subduction zones and intra-plate seamounts. I also use geochemical tracers, such as radiogenic (Sr-Nd-Pb-Hf) and non-traditional stable isotopes (Li-Mg), to study the nature, origin and scale of mantle heterogeneity and their implications to mantle dynamics. Recently, I have interests on the interaction between hydrosphere and lithosphere during seafloor spreading and plate subduction or in hydrothermal/cold seep system, and its related record of magmatism, mineral resources and element cycling.
