Research Foci
Experimental Petrology
I use large volume presses (piston-cylinder, multi-anvil and Paris-Edinburgh press) to reach high pressures (up to 20 GPa) and temperature (up to 2500°C) in order to simulate the inner planets conditions. I studied magma ocean and core formation through metal-silicate partitioning experiments and the primitive martian mantle petrology through phase equilibrium experiments. I am currently studying the properties, in particular the density, of carbon-rich melts (carbonatites, transitional melts and kimberlites) at high pressure and temperature
Numerical study of core formation
I am using numerical tools to understand the formation of the Earth's and other planets' cores. I used numerical simulations to study the segregation of liquid metal from liquid silicate in the conditions of a magma ocean. I also used thermodynamical modeling to study the evolution of temperature of the primitive Earth's core.
