orcid.org/0000-0002-5168-7979From September 2016 I am a postdoctoral fellow working with Dr. Sebastian Hönig at the University of Southampton.
My primary research interest is in galactic hydrodynamics on all scales, from radiation-hydrodynamics models of active galactic nuclei to models of the interstellar medium and the galactic environment. I use AMR and SPH methods to perform these simulations.

Personal
I am a dual New Zealand & British citizen, but I mostly grew up in the beautiful town of Wellington. I currently reside with my wife and baby and a very small puppy in Southampton, UK
