Biography

After completing my undergraduate studies and PhD at the University of Queensland I moved to the UK in 2007 to take up a postdoc at the University of Nottingham. In 2010 I took up a lectureship at Loughborough University and then in 2014 returned to Nottingham in my current position in the School of Mathematical Sciences.

Expertise Summary

I am an applied probabilist, with most of my work being related to biological applications. My specific research interests are as follows:

  • Stochastic epidemic models that are sufficiently simple to admit a reasonable level of mathematical analysis but avoid some/many of the classical homogeneity assumptions; mainly in the SIR framework. More particularly, things associated with networks and other structures, vaccination, approximation(s) of one or more phases of an outbreak (in my rough mental approximation there are 5),
  • Markov processes on a countable state space with an absorbing state; especially questions surrounding the existence and uniqueness of quasi-stationary and limiting conditional distributions, related exponential convergence rates and numerical approximation of quasi-stationary distributions. (This is the area my PhD was in and while it has been on the backburner for some time I do hope and intend to get back to it more seriously.)
