Curriculum Vitae
Research interests
My current research focuses on the role of magnetic helictiy in solar
eruptions, exploiting data-constrained, realistic numerical models of
pre-eruptive configurations. I am particularly interested in combining theory,
observations, and numerical simulations to tackle fundamental plasma physics
problems in magnetized plasmas, like the generation of system-wide currents
from small-scale motions or the role of magnetic reconnection in triggering
coronal instabilities. As most of my research revolves around the properties of
the solar magnetic field, the exploitation of vector magnetograms, in
particular from Solar Orbiter/PHI, the assessment of their reliability and and
their correct disambiguation is key to all such studies. And takes most of my
time.
