  • Research themes:

    I am interested in the use of elemental and isotope geochemistry, as well as magmatic and metamorphic petrology, to understand the formation and evolution of our planet at different scales. My research interests can be summarized in: 1) the formation and evolution of the continental crust, 2) the composition, structure, and evolution of mantle reservoirs, 3) Archean and Hadean geology, and 4) Analytical geochemistry (adaptation or development of new analytical methods concerning both machines and isotopic tools). My major research tool is radiogenic isotope geochemistry, with both long- and short-lived isotope systematics such as Lu-Hf, U-Th-Pb, Hf-W, and Sm-Nd.

    Keywords:

    Radiogenic isotope geochemistry, geochronology, Hadean and Archean Earth, continental crust, mantle reservoirs
