I am a gravitational-wave astrophysicist
I am a gravitational-wave astrophysicist, looking to understand how supermassive black holes in the centers of massive galaxies merge, if at all. I do this by predicting their nanohertz gravitational-wave signatures, which will soon be detected by pulsar timing array experiments. With pulsar timing data, I look for both individual supermassive black holes in binary systems, and for the gravitational-wave background which should be generated by their cosmic merger history.
I am an assistant professor at the University of Connecticut, and an associate research scientist at the Center for Computational Astrophysics (CCA) at the Flatiron Institute. Before joining the CCA I was a Marie Curie International Outgoing Fellow at Caltech and at the Max Planck Institute for Radio Astronomy. I completed my PhD in 2014 at the University of Birmingham (UK) with Alberto Vecchio.

July 2019: New! Discovery of a Close-separation Binary Quasar at the Heart of a z ~ 0.2 Merging Galaxy and Its Implications for Low-frequency Gravitational Waves
These black holes are so big and so awesome that they got their own press release!
18 December: New paper with Lauren Anderson, Megan Bedell and David Spergel, "Improving Binary Millisecond Pulsar Distances with Gaia" Here we improve distances to millisecond pulsars by using its companion's Gaia parallax measurement. Useful for tests of GR, GW detection, and more! All codes on GitHub, https://github.com/ChiaraMingarelli/gaia_pulsars,.
