About

(he/him)

I'm an astrophysics PhD student at the University of Bristol working on accreting compact objects (like black holes), from theory through to numerical simulation and fitting models to data. I'm particularly interested in modelling the X-ray variability around active galactic nuclei (AGN) and X-ray binaries, and in calculating the effects of strong gravity on observational signatures. My thesis is supervised by Andy Young.

I maintain a number of research codes in the Julia programming language, and use Zig for basically everything else.
