Research

I am a member of the Department of Applied Mathematics and Theoretical Physics (DAMTP) and the Astrophysical Fluid Dynamics research group. Broadly, my current research interests include (but are not limited to):

  • astrophysical fluid dynamics
  • magnetohydrodynamics
  • plasma physics
  • general relativity

I am particularly interested in the theory of accretion disks (both around black holes and young stellar objects), including:

  • the launching, collimation and structure of astrophysical jets
  • angular momentum and magnetic flux transport in disks
  • hydrodynamic and magnetohydrodynamic instabilities in disks
  • coherent structures in disks (e.g. vortices, spiral arms, axisymmetric rings and zonal flows)
  • quasi-periodic oscillations (QPOs)

I also have a long-standing interest in homogeneous and isotropic turbulence, and by extension, turbulence subject to various body forces (MHD turbulence, stratified turbulence, gravitoturbulence, turbulence in rotating fluids etc.).
