The main focus of my work is using radiation magnetohydrodynamics to simulate how a molecular cloud core collapses and evolves into a protostar, concentrating on parameter space analyses of the magnetic field geometry and strength and the initial velocity field of the core.

In parallel, I also explore how smoothed particle (radiation) magnetohydrodynamics meth- ods can be expanded and improved, for instance in the presence of very large density gra- dients or complicated magnetic field geometries.
