Carla Tiraboschi

I’m a researcher at the University of Perugia since 2024. I completed my PhD in Earth Sciences at the University of Milan in 2015. Following a postdoctoral position at University of Milan-Bicocca, I joined the University of Münster (Germany) from 2018 to 2024.

As an experimental petrologist, my primary research focuses on the role of volatiles, such as H₂O and CO₂, in upper mantle dynamics, with particular interest in the deep carbon cycle. My work integrates a range of experimental techniques, from piston-cylinder apparatuses to hydrothermal diamond anvil cells, complemented by thermodynamic modeling, to characterize high-pressure fluids and melts and evaluate their potential to mobilize redox-sensitive elements at depth.
