Presentation

I am a ClerVolc post-doctoral research fellow in the Volcanology group of the Laboratoire Magmas et Volcans (LMV), Université Blaise Pascal, in Clermont-Ferrand. My research interests are in the fields of geochemistry, petrology and volcanology.

My PhD in the Laboratory of Interactions et Dynamique des Environnements de Surface, Université Paris XI, focussed on the geochemical properties and the volatiles signatures of magmatic liquids through melt inclusion analysis. More precisely, I worked on olivine hosted melt inclusions from the products of La Sommata (Vulcano, Italy) which are identified as the most primitive products in the Aeolian Arc. Using this example, the aims were to track the abundances, origins and especially the behaviour of water in mafic magma at pre-eruptive levels within the context of subduction.

During my PhD, I specialised in vibrational spectroscopic analytical techniques (FTIR and Raman) and contributed to their improvement in water characterisation in silicate glasses. After my PhD, I obtained a teaching contract at the University Blaise Pascal, and I developed a one year research project in the Petrology group of the LMV. This project was focused on studying, by micro-Raman spectroscopy, the multi scale variability of water in MORB glasses to better constrain the global distribution of water into the mantle. My current post-doctoral research is focused on the determination of volatile contents (H2O, CO2, S, Cl) in phenocryst hosted melt inclusions of Santorini products (Greece). The aims are to better constrain the magmatic storage conditions (P, T), their evolution in time and demonstrate if the geochemical and eruptive style variations are correlated to the volatile content evolution during volcanic history of Santorini Volcano.

Research Topics

Geochemistry (Major, volatile and trace elements) of magmatic products tracking by melt inclusions. Post-entrapment variations in melt inclusions (morphology, composition, water content). microRaman spectroscopy analysis (water content, silicate structure, in-situ analysis).
