Professional Biography

I am a broad-spectrum geochemist with particular interest in geochemical quantitative analysis and their applications, isotope geochemistry and geochronology. I use radiogenic isotopes and incompatible trace element geochemistry to infer the source and depth of melting in rifting environments with the ultimate goal of better understanding the role of magmatism in the early stages of rifting.

I have experience performing high-precision 40Ar/39Ar step-heating geochronology; SEM, EMPA, ICP-OES, LA-ICP-MS, and MC-ICP-MS measurements (P54, Neptune and Nu). Additionally, I am trained on pXRD, uXRF and Raman Spectroscopy.
