- 1989: Degree in Geological Science with a vote of 110/110 (University of Florence).
- 1993: PhD in Mineralogy and Petrology (Consortium of the Universities of Florence and Perugia).
- Deep knowledge of fluid inclusions and several analytical methods for their study.
- Applications of mineralogical-petrographic studies, analyses of fluid inclusions and stable isotopes to:
- geothermal researches
- genesis of mineral deposits, hydrothermal industrial rocks and pegmatites
- thermo-barometric reconstructions in metamorphic and magmatic environments
- studies on fluid migration in geological structures
- researches on CO2 mineralogical and geological sequestration.
- Experimental laboratory researches on fluid inclusion synthesis and fluid-rock interaction studies.
