Research

Research interests

My research focuses on the use of in-situ analytical methods (principally SIMS and LA-ICP-MS) to investigate the geochemical systematics of fluid-rock interaction from seafloor hydrothermal systems, through subduction and during ultra-high-pressure metamorphism.

To better constrain processes active in the uppermost subducting slab, I'm currently investigating the boron and oxygen isotope systematics in metasediments, metabasalts and serpentinties from the Lago di Cignana Unit and underlying Zermatt-Saas Ophiolite (NW Italian Alps). Here we hope to constrain the timing and extent of fluid infiltration within the unit, and better understand the fluid-mediated interactions between common lithologies in the slab. For this purpose, I have been developing standard operating routines for boron isotope analysis by SHRIMP, with the assistance of the technical staff here at RSES. 

As part of the International Ocean Discovery Program (IODP) Expedition 357 - Atlantis Massif: Serpentinization and Life and in collaboration with Daniela Rubatto and Mark Kendrick, I'm also working on serpentinized ultramafic rocks within an active seafloor hydrothermal system adjacent to the Mid-Altantic Ridge. We will attempt to constrain active (or previously active) fluid-rock interaction processes associated with the oceanic detachement fault using halogen, noble gas and in-situ oxygen isotope analysis.
