On 01/09/2022, we welcome to ISTO Kenneth Koga, PU assigned to the Magma team. Specialized in experimental geochemistry at high temperature, Kenneth measures geochemical fractionations related to magma genesis, metamorphism, metasomatosis. The objective is to understand the geochemical cycles of magmatic volatile elements. In parallel, it studies experimentally the geochemical equilibria and kinetic processes in liquid-mineral interactions during fluid migration, at different scales.
