OSTORERO LEA EMMA RACHEL
Biography
I am a postdoctoral researcher at the University of Milano-Bicocca since March 2023. I study volatiles released by Neo-Tethyan magmas and the impact of magmatic CO2 emissions on Early Cenozoic climate changes via melt inclusions. I work in the Coupled Earth Systems (CoSy) research group led by Prof. Pietro Sternai, under the international research project MATRICs: MAgmatic TRIggering of Cenozoic Climate Changes. The main objective of the project is to quantify how changes in magmatic CO2 emissions have influenced the Earth's climate during the last 66 million years. To this end, I perform heating experiments and SIMS analyses of melt inclusions from andesites and rhyolites of Himalaya, Tibet and Iran to help us constrain the pre-eruptive volatile budgets of these areas.
I obtained my PhD in volcanology in 2022 at the Institut de physique du globe de Paris/Université Paris Cité (France). My PhD focused on spatio-temporal dynamics of magmatic plumbing systems before eruptions in Dominica island (Lesser Antilles) and Kamchatka (Russia).
