Scale-dependent alignment in compressible magnetohydrodynamic turbulence
Scale-dependent alignment is how turbulence connects to reconnection. We show that the nature of scale-dependent alignment in compressible turbulence differs from well-established incompressible theory.

Density FluctuationâMach Number Scaling in Compressible, High Plasma Beta Turbulence: In Situ Space Observations and High-Reynolds Number Simulations
We compare in situ space observations of Earth's magnetosheath with high resolution data showing that the density fluctuations follow a linear relation with Mach number in both.

Taking control of compressible modes: bulk viscosity and the turbulent dynamo
I've been interested in exploring the nature of different types of viscosity and the role it plays in the dynamo for some time! This is my latest work on trying to marry bulk viscosity -- the type of viscosity generated by out-of-thermal-equilibrium vibrational degrees of freedom (only possible in poly-atomic plasmas) -- and the turbulent dynamo, giving rise to a whole new range of scales -- the sub-bulk-viscous range.
