Dr. Alessandro Vona
Career
2011 – PhD in Environmental and Resource Geology, Roma Tre University.
Thesis: "Multiphase Rheology of Italian Alkaline Magmas". Tutor: Dr. Claudia Romano.
2005 – M.Sc. in Geological Sciences at Università di Roma Tre
Thesis on "Indagini sperimentali sulla cristallochimica dei clinopirosseni e assimilazione carbonatica". Tutor: Prof. Annibale Mottana.
Research activities (Mineralogy, Volcanology, Geochemistry):
