My research interests focus on compact objects; the remnants of stars in the form of white dwarfs, neutron stars and black holes. Binaries involving one or more compact remnants offer spectacular laboratories for a broad variety of astro-physics. Such binaries are responsible for spectacular explosions and are principal source of gravitational waves. I am interested in the astrophysics enabled through gravitational waves as well as what can be learned from combined GW & electromagnetic information, aka multi-messenger astronomy.
I am an observationally focused astronomer, exploiting the spectrum of facilities available to us, both from the ground as well as space. I am currently leading a new facility that will hunt for EM signatures of binary mergers, called the Gravitational wave Optical Transient Observer (GOTO).
If you are interested in a Ph.D position in our group, a description of current projects on offer can be found here.
