I am using the geochemical composition of minerals to gain insights into crustal processes such as fluid flow, element mobility (e.g., base metals), and the behavior of halogens and other volatiles during metamorphic processes in order to better understand their global cycles. In order to unlock geochemical archives of minerals, I use a wide range of micro-analytical methods including SIMS, FTIR, EPMA, LA-MC-ICP-MS.
