Research interests:

I am an experimental mineral physicist studying the chemistry and thermodynamics of Earth and planetary deep interiors. I specialize in the combined use of synchrotron single-crystal and powder diffraction techniques in the diamond anvil cell to explore petrological systems at multi-megabar pressures and temperatures (P-T) Currently in my postdoc, I am investigating high P-T post-post spinel transitions, iron charge ordering and cation partitioning in oxides and silicates, and the mineralogy of natural and synthetic diamond inclusions. This crystallographic research contributes to our understanding of the mantle structure of super-Earths, the chemistry and dynamics of Earth’s deep interior, and the formational environments of diamonds in Earth’s mantle.
