Research
I am interested in planetary materials broadly: rocks, minerals, metals, and ices. Their microscopic properties control how planets are built and how they change over time. My group uses laboratory experiments and computer simulations (e.g., multianvil presses, diamond anvil cells, molecular dynamics, thermodynamic modeling, machine learning) to connect that physics and chemistry at the atomic scale to what we actually observe in Earth and other planets, geophysically, geochemically, and astronomically.
Current topics of interest include:
Phase transitions of planetary materials
Water in the habitability of rocky planets
Structure of giant planets and exoplanets
→ Information for prospective students and postdocs.
Selected Publications
Nonlinearity of the post-spinel transition and its expression in slabs and plumes worldwide.
