I received my doctorate in Physics at the University of Palermo (Italy) on the topic of coronal activity in the Sun and other stars. After my graduate studies I held a post-doctoral appointment at the Kavli Institute for Astrophysics at MIT. My research focuses on understanding the heating mechanisms and X-ray emission processes in the hot outer layers of the atmosphere of the Sun and other stars, by combining observations with advanced numerical modeling. My interests encompass a wide range of astrophysical sources including the Sun, late-type main/pre-main sequence, and early-type stars. I am also involved in development and operations of space instrumentation, as co-I or instrument team member of several missions and of rocket experiments, including the Interface Region Imaging Spectrograph (IRIS), the Hinode X-ray Telescope (XRT), the SDO Atmospheric Imaging Assembly (AIA), the Marshall Grazing Incidence X-ray Spectrometer (MaGIXS), and the Hi-resolution Coronal Imager (Hi-C).
