I work broadly within the realm of gravitational-wave astronomy. Nearly infinitesimal ripples in the fabric of spacetime, gravitational waves are generated by the most cataclysmic events in the Universe, including the explosions of stars and the relativistic collisions of black holes. My interests lie in the use of gravitational waves as tools with which to explore the binary neutron star and black hole population, probe the astrophysical and cosmological gravitational-wave backgrounds, and test our understanding of fundamental physics. I am a member of the LIGO Scientific Collaboration, in which I co-chair the "Astrophysical Rates & Populations" group responsible for inference and analysis of the gravitational-wave source population.
