Daniel Holz

Daniel Holz's research focuses on gravitational waves—ripples in the fabric of space-time created by powerful events like black hole collisions—with a particular focus on what we can learn about physics, astronomy, and cosmology from our detections.

Holz is a member of the Laser Interferometer Gravitational-Wave Observatory (LIGO), which made the first detection of gravitational waves. In 2006 Holz was the first to suggest the concept of calculating the Hubble constant - the rate at which the universe is expanding—via gravitational waves, and he was among the authors who published the first calculation of such a "standard siren" in the wake of the 2017 detection of a neutron star collision.
