I am a professor in the Department of Mathematics at the University of Aberdeen.

I did my undergraduate degrees (BSc (Hons) in Mathematics and Physics) in the Department of Mathematics and Statistics and the Department of Physics at the University of Otago. I did my PhD in Mathematics in the Mathematics Department at King’s College London, under the supervision of Dr Luke Hodgkin. Since then I have done postdoctoral research in the former School of Mathematical Sciences – now the Mathematical Sciences Institute – at the Australian National University, in the School of Mathematics and Statistics at the University of Sydney, and in the Institute of Mathematics at the Hebrew University of Jerusalem. I was a lecturer for a year in the Department of Mathematics at Macquarie University and a Research Associate for a year in the Institute (now School) of Mathematics, Statistics and Actuarial Science at the University of Kent. From 2004 to 2011 I was a lecturer in the Department of Mathematics and Statistics at the University of Canterbury. From 2011 to 2014 I was an Associate Professor in the Department of Mathematics at the University of Auckland.
