When seismic waves travel through Earth’s deep interior they probe the physical properties of the materials that compose Earth’s mantle and core. I use high-pressure experiments to determine the elastic and thermodynamic properties of candidate materials and model their seismic properties at pressures and temperatures of Earth’s deep interior. The results of mineral-physical experiments and models can be combined with geophysical observations to explore the composition and thermal state of the mantle and core that ultimately control the geodynamic evolution of the deep Earth.
