Node PI
Enrico Barausse
Full professor in the Astroparticle Physics group at SISSA and Principal Investigator of the SISSA node of GWSky. A relativist working on the physics and astrophysics of gravitational waves and their sources — black holes and neutron stars — and on theories of gravity that extend General Relativity. On GWSky, the SISSA node studies how the astrophysical environment imprints on gravitational-wave signals, tests alternatives to Einstein gravity, and develops statistical and machine-learning methods for next-generation detectors.
