BSc(Hons), PhD (Cantab)


I did my undergraduate studies in Australia, my PhD in England. I have held postdocs in Ghent (Belgium), Chennai (India), Bristol (UK) and the Open University (UK). In 2014 I was a visiting professor at the Universidad de Costa Rica. In Jan 2015 I started work as a lecturer at USW.


I am the lead for the Mathematical Sciences Research Group.

My research is in group theory, a branch of algebra. Put another way, group theory is the mathematical study of symmetry; my main focus is on finite groups.
