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
