Chiara Mingarelli is a gravitational-wave astrophysicist who is looking to understand how supermassive black holes in the centers of massive galaxies merge, and if they merge at all. She does this by predicting their nanohertz gravitational-wave signatures, which will soon be detected by pulsar timing array experiments. With pulsar timing data, she looks for both individual supermassive black holes in binary systems and for the gravitational-wave background, which should be generated by their cosmic merger history. Before joining the Center for Computational Astrophysics, Mingarelli was a Marie Curie International Outgoing Fellow at the California Institute of Technology and at the Max Planck Institute for Radio Astronomy. She completed her Ph.D. at the University of Birmingham in the United Kingdom with Alberto Vecchio.
