Black Hole

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

I'm a third year PhD student in the Astrophysics sub-department at the University of Oxford, under the supervision of Rob Fender and Ian Heywood.

I am primarily interested in observing some of the most extreme environments in the Universe, such as those around black holes and neutron stars. We do this to strenously test our phsyical theories in extreme environments and to better understand the nature of these unusual objects.
