Research

I have been laying the foundations of gravitational wave astronomy since the days most people said it would never happen.  I am one of very few people who has worked on all four types of signals (binary mergers, continuous waves, stochastic background, non-binary bursts), both theory and data analysis.  LIGO's historic discoveries of binary mergers used my mathematical techniques for covering parameter space and evaluating waveform accuracy, and I have also worked on analytical and numerical waveforms.  I discovered the most promising  emission mechanisms for continuous waves, astrophysically guided many LIGO searches, and run big searches myself.  Many types of LIGO burst searches bear my fingerprints, particularly searches for starquakes.

With binary merger detections becoming routine, I am focused on the yet undetected signals that define the new frontier.  Continuous waves present the greatest mathematical and computational challenges, their searches are most affected by electromagnetic astronomy, and they can tell us uniquely about the microphysics of dense matter; so they are the type that gets most of my attention these days.  I am also interested in all sorts of novel signals, particularly those involving neutron stars.

I am the head of observational data and computing for Cosmic Explorer, a planned improvement on LIGO.
