Research

I'm interested in the universe. Of all the ways that we may come to learn more about the universe in the next decade I believe the most transformative will be gravitational wave observations combined with more conventional observational modalities. The focus of my research is thus on speeding that moment when gravitational waves will be detected directly and developing the analytic and inferential tools that will allow us to fully exploit that detection to learn about the cosmos. I'm involved in all the major projects whose aim is the direct detection of gravitational waves – LIGO, LISA and NANOGrav – and how we may use observations with these or similar detectors to improve our understanding of gamma-ray bursts, binary stellar populations and evolution, the formation and evolution of galaxies and the structure of our own galaxy, and even, perhaps, gather clues that will help us understand how nature reconciles gravity and quantum mechanics.
