Justine did her Bachelor and Master degrees at the foot of volcanoes in Clermont-Ferrand, France. She studied petrology, geochemistry, volcanology and geophysics. She had several internships where she used laboratory experiments with high pressure and high temperature. These experiments allowed her to investigate the processes that occur in magmatic chambers of different volcanoes such as Puy de Sancy, France, Cappadocian Supervolcano, Turkey and some East African Rift Valley volcanoes. She is now a PhD student working at the Dipartimento di Scienze della Terra in Milan, Italy. There she works uses laboratory techniques to reproduce processes going on between magma and solid rocks, at the mantle-crust interface in ridges regions. She will mainly write about lab devices, experimental and analytical techniques and the mantle.
