As the leader of the experimental gravity group at Columbia, he is looking into what happens when two black holes or neutron stars merge in the distant universe, and is collaborating with the Laser Interferometer Gravitational Wave Observatory, a facility funded by the National Science Foundation and located in Louisiana and Hanford, Wash. that aims to detect cosmic gravitational waves.
