My research interests focus on the generation of magma beneath volcanoes. I am interested in what causes magmas to form, especially in continental collision zones, and what their erupted products can tell us about Earth's mantle. In particular, I like to better constrain the chemical heterogeneity of magma sources, and to what extent Earth's crust is being recycled in subduction zones.
To do this, I study the geochemistry of tiny droplets of magma trapped inside growing crystals. These melt inclusions are shielded from outside processes during magma ascent, so they provide unique snapshots of magma compositions at deep levels. Such inclusions in olivine—one of the earliest-forming magmatic crystals—store crucial information about the deep origin of magmas that is often invisible in bulk lavas.
