I completed my PhD degree in 2005, working under supervision of Professor Alan Beardon at the University of Cambridge. I was then a post-doctoral researcher for three years at the National University of Ireland, Maynooth, working with Professor Anthony O'Farrell. After that I worked with Professor David Spiegelhalter and Mike Pearson at the University of Cambridge on the Understanding Uncertainty project. In 2010 I obtained a lectureship in mathematics at the Open University, a job that I still hold today.
My research interests include continued fraction theory, complex dynamics, and hyperbolic geometry.
I'm the chair of the undergraduate module M337 Complex analysis and the graduate module M829 Analytic number theory II. I'm also the chair of production of the revised version of M337.
