Fields of Interest

Subduction zones play a key role in creating and maintaining the habitable Earth. As igneous geochemist I pursue integrative geochemical and geological studies in global volcanic arcs with the goal to understand how processing of crust and mantle materials in subduction zones shape the arc magmatic fluxes and assess their potential to influence the broader geochemical cycles of Earth.
