I am a PhD student in the Experimental Petrology group. My research aims to investigate advanced melting, deformation, and extraction of liquids from very hot ancient mantle through experimental petrology. The main aim of my project is to conduct high P experiments to inform thermodynamics activity-composition models for mantle minerals and liquids at P-T-X conditions relevant to the Archean mantle.
Previously, during my master's degree, I focused on mantle metasomatism and refertilization caused by different melt compositions in the SCLM. However, during my honours I studied whole-rock geochemistry, mineral chemistry and structural data of felsic metavolcanic rocks from a fold and thrust belt to understand their origin and evolution.
