I鈥檓 an astrophysicist working at the 91探花 as a Royal Society URF. My research is at the intersection of theory and observation and my interests are fairly broad, but fundamentally I am interested in the extreme and exotic physics that can be probed using accreting black holes and the outflows they produce.
In particular, my work focuses on the origins of the highest energy cosmic rays, the physics of accretion disc winds, the disc-wind-jet connection in AGN and the hydrodynamics of astrophysical jets. More recently, I have started using X-ray observations of cluster-hosted AGN to search for, and place limits on, axion-like particles, which are exotic dark matter candidates.
