Hello!

I am a statistics PhD candidate at the University of Auckland, where I spend my time researching and developing statistical models that can applied to the sport of cricket.

This webpage is currently a work in progress but feel free to take a look around at my past and present work.

Research

I completed my Bachelor of Science at the University of Otago in 2014, majoring in statistics and minoring in Psychology. In 2015 I returned to my hometown of Auckland, where I have been studying statistics at the University of Auckland since.

Following on from the work I did as part of my Masters, I began a Doctor of Philosophy in mid-2017, focussing on statistical applications in cricket, this time collaborating with the national cricketing board, New Zealand Cricket.

In 2017 I completed my Masters degree under the supervision of Dr Brendon Brewer. My research looked to tell a more meaningful story behind a cricket player’s batting average. Using Bayesian statistical techniques, I explored more in-depth methods of quantifying a cricketer’s batting ability than the simple batting average. More specifically, I built statistical models which describe how well a batsman is playing at any given point in their innings, allowing us to quantify the cricketing idea of a batsman ‘getting their eye-in’. The primary focus was on Test match cricket, with wider applications to 4-day First Class cricket. Using these models, I explored the plausibility of popular cricketing superstitions from a statistical point of view, such as the commentator’s favourite, the ‘nervous 90s’.

ABSTRACT: At a glance, data is more meaningful when presented in graphical form. This project explored innovative methods of automating the display of catch data for large-scale conservation projects. High priority was given to developing methods that allow users to interact with their data, affording them some control over the graphics that are produced. Two interactive applications were developed that allow conservation volunteers to select the data they want to view and how to view it. After a day in the field, volunteers are able to use these applications to see their day’s work summarised on a map or graphic. These graphics highlight the positive impact their efforts are having on the local environment, keeping volunteers motivated and engaged in their work. Various methods of improving the automation of these graphics are outlined, as well as other practical uses of these statistical applications.
