My research interests include:

• High energy astrophysics including relativistic astrophysics, radio, X-ray and gamma-ray astronomy
• The formation and propagation of jets and their interaction with the host environment; AGN feedback
• The magnetic structure of accretion discs in AGNs and its relationship to coronal emission and jet formation
• Astrophysical gas dynamics (inc. turbulence and magnetohydrodynamics)
• Computational astrophysics
