Research Overview
My research explores the formation and evolution of terrestrial planets, focusing on the processes that shape their interiors. To address these topics, I combine data from stable isotope geochemistry with insights gained from high-pressure and high-temperature laboratory experiments.
A central theme of my work is understanding how mass-dependent isotope fractionation occurs in high-temperature environments. Analysis of mass dependent stable isotope variations offers a powerful tool for studying planetary interior processes, including mantle melting, magmatic differentiation, and the formation of continental crust.
Current Projects
- Developing experimental calibrations for trace element and isotope fractionation between minerals and melts at high temperature and pressure conditions.
- Applying stable isotope techniques to investigate continental crust formation across different geodynamic regimes, from the Archean to the present day.
- Exploring high-temperature stable isotope fractionation within Earth's mantle.
