Here you can find a PDF with my Curriculum Vitae, updated to January 2020.
I am a postdoctoral researcher in high energy astrophysics. I study the physics of accretion and ejection of matter around supermassive black holes, and their connection to galaxy formation and evolution. I mainly use data collected with X-ray and UV detectors onboard space telescopes, and I am especially interested in the state of the art and the future developments of spectroscopic techniques.

After getting my B.Sc., M.Sc., and PhD in Astronomy at the University of Bologna, I worked as postdoctoral researcher in several institutes in different countries, before landing at the Centro de Astrobiología where I work these days. I also had the chance to spend several months as visiting scholar and researcher in Universities and Research Institutes abroad.

In order to study phenomena happening close to supermassive black holes in distant galaxies, astronomers need UV and — especially — X-ray data. Such data can be harvested in the enormous existing archives, or new data can be obtained through new observations, to be requested in international calls open to observing time proposals.
I am the Principal Investigator of six successful proposals with XMM-Newton, Chandra, the Hubble Space Telescope (HST), and the Very Large Array (VLA).

The data collected through space telescopes are analyzed and the results of the analysis are published in refereed scientific journals. During the process of elaboration of the results, preliminary parts of the studies are usually presented and discussed in seminars and colloquia given at Universities, Research Centers, conferences and meetings. This implies a lot of traveling.
