Research

My major research interests include general relativity, relativistic astrophysics, and computational astrophysics.  I am engaged in a long-term project to solve Einstein's equations of general relativity by computer.  One of the goals of this project is to predict the gravitational wave form from coalescing black holes in binary orbit about each other.  An exciting moment was when our wave form was used to compare theory with experiment in the first detection by the Laser Interferometer Gravitational Wave Observatory (LIGO). My recent research has spanned many other topics in relativistic astrophysics. I have worked on naked singularities in general relativity; the properties of rapidly rotating neutron stars, including possible observational signatures in pulsars; exploding neutron stars; relativistic stellar dynamics, and planets around pulsars.  Most of this work is done in collaboration with other members of the Theoretical Astrophysics Group, including graduate students.
