  • Masayo Minami, Institute for Space–Earth Environmental Research, Nagoya University, Japan ; email: gj@geochem.jp

    My primary interests are in chronology and isotope geochemistry. I apply a variety of isotopes, including radiocarbon and Rb-Sr isotopes, to environmental, archaeological, and geological materials. Through the chemical and isotopic analysis, I aim for a better understanding of the Earth and human histories, and the dynamic processes of the Earth’s surface materials.
