Research

I am interested in physical and chemical processes of the Earth’s interior through high-pressure and high-temperature experimental petrology and mineral physics. So far, I have focused my work on the study of the deep carbon cycle looking at possible carbon-bearing minerals and carbonates stability in the Earth's lower mantle.

Experimental techniques :

Laser heated diamond anvil cell (Mao and Chervin cells), cold-seal hydrothermal pressure vessels and high volume autoclaves

Analytical techniques :

I use both in situ and ex situ analyses.

Synchrotron based in situ X-Ray diffraction (done at high-pressure and high-temperature) and  X- ray Emmission Spectroscopy, Raman spectroscopy and infrared spectroscopy.

ex situ 4 circles X-Ray diffraction, Scanning transmission X-Ray spectroscopy (STXM) (at synchrotron), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), electron microprobe and Focused Ion Beam (FIB) preparation.
