Emanuele Berti

Emanuele Berti is a Professor of Physics at Johns Hopkins University, specializing in gravitational physics and gravitational-wave astronomy. He holds a PhD from the University of Rome “La Sapienza” (2002) and has held postdoctoral positions at institutions including the Institut d’Astrophysique de Paris and JPL/Caltech. He joined JHU in 2018 after serving on the faculty at the University of Mississippi. His research focuses on black holes, neutron stars, modified gravity theories, and gravitational-wave observations with LIGO/Virgo and future missions like LISA. He is an APS Fellow, ISGRG Fellow, and served as Chair of the APS Division of Gravitational Physics (2016–2019). Currently, he is President-Elect of the ISGRG and an Associate Editor for Physical Review Letters. He teaches courses like General Relativity (AS.171.646) and leads research initiatives such as the GSSI-JHU MAECI collaboration on gravitational wave astrophysics. His work includes analyzing quasinormal modes of black holes, testing general relativity with gravitational waves, and exploring the astrophysical implications of compact object mergers.

His research interests span theoretical and observational aspects of gravitational physics, including the dynamics of black holes and neutron stars, gravitational-wave signatures of alternative gravity, and the interpretation of LIGO/Virgo data. Recent work emphasizes “black hole spectroscopy”—using ringdown signals to probe spacetime geometry and test Einstein’s theory. He has co-authored groundbreaking studies on hierarchical black hole mergers and received the 2025 Frontiers of Science Award for his 2017 paper on binary black hole formation channels. His collaborations include NASA’s U.S. LISA Study Team and international projects like the GSSI-JHU meetings in L’Aquila and Baltimore.

Notable contributions include computational tools for quasinormal mode calculations, data repositories for Kerr black hole perturbations, and pedagogical materials for graduate-level relativity courses. His work bridges theoretical frameworks with experimental insights, leveraging both numerical simulations and observational data. Current efforts aim to prepare for upcoming detector upgrades and address challenges in interpreting gravitational wave signals from space-based observatories.
