Biography

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 Prof. D.R. Heath-Brown.

I once took 6/24 in a college cricket match bowling an optimistic variety of medium-pace. I rather suspect that the opposition reversed their batting order.

During 2009-2010 I was a Lecturer in Mathematics at Merton College, Oxford. During 2010-2012 I was a postdoctoral research fellow at the University of Lethbridge.

Researcher's projects

  1. Sign changes in some arithmetic functions (with Amir Akbary, Lethbridge)
  2. The first sign change in Mertens' formula (with Yannick Saouter, CNRS and Patrick Demichel, Hewlett-Packard France)
  3. Quadratic polynomials over primitive roots (with Stephen Cohen, Glasgow, and Tom\'{a}s Oliveira e Silva, Aveiro)
  4. Diophantine quintuples (with Dave Platt, Bristol)

Available student projects

The following is a brief list of some honours and undergraduate projects. Please email me for more information.

Some general topics that provide an introduction to analytic number theory are

  1. The theory of the Riemann zeta-function
  2. Waring's problem
  3. Computational searches for specific primes

Some specific topics are

  1. Turan's power sum method
  2. The failure of the Mertens conjecture
  3. Explicit zero-free regions of the zeta-function and other L-functions
  4. Skewes' Number for Mertens' theorem
