RESEARCH TOPICS
I study the cycle of volatile elements in subduction zone settings to try to understand why and how volcanoes erupt the way they do. I use melt inclusions to get to the volatile compositions of the less degassed source of arc magmas, but also of mid-ocean ridge and hot spot magmas. I am an isotope geochemist by education and use stable isotopes and their fractionation to study magma degassing and magma mixing. I use volatile element diffusion in embayment to calculated magma ascent rates. All of my research themes involve in situ analysis which I perform by using SIMS, nanoSIMS, LA-ICPMS, and EMP.
