Research interests: Two black holes in a close orbit about each other emit gravitational waves, which might be detectable by the LIGO or LISA projects within the next ten years. But, at this time, we know surprisingly little about the details of the final coalescence of the black holes. In particular, we are ignorant of how the amplitude and frequency of the radiation change with time. Knowledge of these details would aid immensely in our search for gravitational waves.Select Publications
