I graduated from the Australian National University in 2005, and received a General Sir John Monash Award to study overseas. In early 2010 I was awarded my DPhil from the University of Oxford, having studied under Professor D.R. Heath-Brown. From 2009-2010 I was a Lecturer in Mathematics at Merton College, Oxford. From 2010-2012 I was a postdoctoral research fellow at the University of Lethbridge.

My main focus is the Riemann zeta-function.
