About

My PhD was in physics but I moved into statistics courtesy of an EPSRC (UK) Statistics Mobility Fellowship. I have been a member of the Department of Mathematics and Statistics since 2011.

I am currently a principal investigator at Te Pūnaha Matatini Centre for Research Excellence. I am deputy leader of NZ Science Group, which is part of the Laser Interferometer Space Antenna (LISA) Consortium. I am also a past President of the NZ Statistical Association (2020–2022).

Teaching responsibilities

My teaching responsibilities include:

STAT 312 Modelling High Dimensional Data
STAT 372 Stochastic Modelling
STAT 405 Probability and Random Processes
INFO 420 Statistical Techniques for Data Science

Research interests

My research expertise is mathematical and statistical modelling. My research is currently focused on applications of scoring rules in statistics, modelling epidemics in plants and human populations, analysis of solar storms and geomagnetic events, statistical analysis of gravitational waves, modelling of methylation and epigenetic modification, and the development of new algorithms for statistical inference. These activities are strongly influenced by my background in physics and computational methods.

I am actively looking for Honours and postgraduate students to work on projects in these areas. I value mathematical and computational ability as much as I do statistical background.
