  • Research interests:

    Specialized in experimental high-temperature geochemistry.

    • Interested in determining geochemical fractionations during magma genesis, metamorphism, and metasomatism in Earth mantle. My current focus is to understand the geochemical cycles of magmatic volatile elements.
    • Geochemical equilibrium & kinetics processes of liquid – mineral interactions during fluid migration in subduction zone investigated by high pressure – high temperature experiments
    • Light isotope fractionation under high-pressure high-temperature conditions using empirical and mineralogical measurements
    • General geochemical kinetics processes associated with Earth sciences (Diffusion process in diamond, and silicate minerals; reaction kinetics of silicate systems)
    • Micro-scale geochemical observations and their relationships to geochemical kinetics
