Research interests:

I study the physical and chemical properties of materials under high pressure and high temperature conditions, to better understand the constitution, structure, and evolution of the Earth's interior. Specifically, I am interested in the distribution of long-lived radioactive elements in the deep Earth and how it affects the heat structure of the planet through time.
