I was born in London and moved to Australia in 1991. My main research interest is Cosmology. In particular for the last few years, I have worked on whether the laws of Nature vary in space or time. My colleagues and I began our work in this area in 1998 and in 1999 we published the first hints that alpha, the fine structure constant, might not be constant. Alpha represents the strength of the electromagnetic force. Following that we have published many papers on the subject, and recently, we have used a large amount of data from the Keck and VLT telescopes to look into the matter in more detail. We have found that the data suggests that alpha varies smoothly with position in the sky, and that the data fit a dipole model, i.e. in one direction alpha increases, and in the opposite direction it decreases.
