Giacomo Fragione graduated cum laude in Astronomy and Astrophysics under the supervision of Prof. Alessandro Melchiorri, working on satellite Planck data. He was a fellow of the joint Ph.D. program in Astronomy, Astrophysics and Space Sciences of the Sapienza University of Rome and the University of Rome Tor Vergata. His dissertation, entitled "Hypervelocity Stars as Tools for Galactic Astrophysics," was developed under the supervision of Prof. Roberto Capuzzo-Dolcetta.
At present, he is both a Foreign Postdoctoral Fellow of the Israel Academy of Sciences and Humanities and an Arskin Postdoctoral Fellow at the Hebrew University of Jerusalem, where he works with Prof. Re'em Sari, researching the dynamic evolution of dense stellar environments as globular clusters and galactic nuclei. Recently he has been working on the gravitational waves produced during the mergers of black holes and neutron stars and on the characteristics of the planetary systems in binary and triple stars.
In 2019, while an IASH Postdoctoral Fellow at the Hebrew University, Giacomo published more than 15 papers in the major international astrophysical journals on a number of fields, including intermediate-mass black holes, hypervelocity stars, black hole and neutron star mergers and dynamics of exoplanets. He went on to be a CIERA Postdoctoral Fellow at CIERA Northwestern University.
