Associate Professor
Jose Maria Ezquiaga is an Associate Professor at the Theoretical high energy, astroparticle and gravitational physics section of the Niels Bohr Institute (NBI), University of Copenhagen's Faculty of Science. He joined NBI as an Assistant Professor in 2022 and was subsequently promoted to Associate Professor. Prior to his position at Copenhagen, he held a prestigious NASA Einstein Fellowship at the University of Chicago. His work focuses on exploiting gravitational wave data to explore fundamental physics questions at the intersection of cosmology and astrophysics. PhD from Universidad Autonoma de Madrid (2019) NASA Einstein Fellow at University of Chicago Associate Professor at Niels Bohr Institute (2022-present) Dr. Ezquiaga's research centers on probing gravity and unveiling the nature of dark energy and dark matter through gravitational wave observations. His work spans gravitational lensing of gravitational waves, black hole formation mechanisms, primordial black holes as potential dark matter candidates, and cosmological applications of gravitational wave data. He actively investigates how gravitational wave observations can test general relativity and alternative theories of gravity in extreme regimes. His recent publications (2023-2025) demonstrate a strong focus on gravitational lensing effects in gravitational wave astronomy, with particular attention to waveform distortions, identification techniques, and cosmological applications. His work on spectral sirens and cosmology from gravitational wave data represents an innovative approach to measuring cosmic expansion without traditional astrophysical assumptions. NASA Einstein Fellow Member of LIGO Scientific Collaboration Member of LISA Consortium Member of Cosmic Explorer Collaboration As a member of multiple major international collaborations including LIGO, LISA, and Cosmic Explorer, Dr. Ezquiaga contributes to both theoretical development and observational analysis in gravitational wave astronomy. His research group focuses on developing novel techniques for extracting cosmological information from gravitational wave signals and testing fundamental physics through multi-messenger observations. He has been involved in numerous significant discoveries related to gravitational wave lensing and its implications for cosmology and fundamental physics.
