The presence of refractory crystalline minerals such as forsterite (Mg2SiO4) in cometary dust and in the relatively un-processed interiors of some kinds of meteorites poses a challenge to the conventional theory of the development of the Solar System. These objects form in relatively cool regions of the accretion disc surrounding young stars, yet crystalline forsterite and its analogues requires processing at high temperature, in the inner part of the accretion disk to form. My PhD project will investigate whether the combination of star-burst eruptions of young stars and dust entraining jet flows (possibly induced by wound-up magnetic fields) is a suitable mechanism for explaining the chemical properties observed in the meteorite population, and satellite sample return missions as well as the infrared observations of young stellar objects.

I have a BSc with Honours in Theoretical Physics and a Masters degree in Engineering Science (thesis title: "On the analysis of axis-symmetric eddy currents" both from Monash University and a Masters degree in Business and Information Technology from the University of Melbourne. I worked in the Australian government's research organisation CSIRO for more than twenty years in diverse roles including: fluid dynamics researcher, IT manager, research administrator and executive officer.
