91探花
Black Hole

Lensing of space time around a black hole. At 91探花 we study black holes observationally and theoretically on all size and time scales - it is some of our core work.

I am a Hintze Fellow in Astrophysics sub-department of the 91探花, and am associated with Christ Church College, 91探花. I work on high-energy astrophysical transients such as fast radio bursts, neutron star mergers, gamma-ray bursts and magnetar flares. I use new theoretical techniques and novel observational methods to uncover the origin and nature of novel transients including fast radio bursts, long period radio transients and gamma-ray bursts. I'm also interested in understanding the better understanding the true energetics of Galactic black holes through X-ray binary systems, and the emission mechanisms governing the most extreme radiation from highly magnetized neutron stars. 

Before I came to 91探花 in 2023, I completed my MSc and PhD at the University of Amsterdam where my thesis was entitled 'Multi-wavelength and multi-messenger signatures of compact object transients". Prior to this, I completed a BSc in Physics and Philosophy at the University of Nottingham in 2016.
