Brief Biographical Sketch

Hello, and welcome to my website. I'm a theoretical astrophysicist at NASA's Jet Propulsion Laboratory (JPL) and the TAPIR group at Caltech. My research is focused on gravitational waves — ripples in the gravitational field that propagate through space and time — and the sources that produce them: colliding black holes, neutron stars, supernovae, and other exotic phenomena.
