Biography

I am a lecturer in the Department of Statistics at the University of Auckland, New Zealand, having joined in January 2017.

I originally completed BSc (Hons; in statistics and psychology) and MSc (in statistics) degrees at the University of Auckland. In 2016, I graduated with a PhD from the University of St Andrews, United Kingdom, completed under the supervision of Professor David Borchers. I remained there for twelve months as a research fellow, funded by the award of an EPSRC Doctoral Fellowship Prize.

I develop statistical methods and the associated software to estimate ecological parameters of interest, usually animal abundance or density. I am currently working on new spatial capture-recapture methods, and modelling uncertain animal identification on capture-recapture surveys.

A comprehensive CV is available here.

Software

The R package ascr fits a range of acoustic spatial capture-recapture models. Find its homepage here.

The R package palm fits various point processes via maximisation of the Palm likelihood, and is available on CRAN. Find its homepage here.
