Biography

I completed BSc (Hons) and MSc degrees at the University of Auckland before moving to the University of St Andrews, United Kingdom, where I graduated with a PhD in 2016. I remained at St Andrews for a twelve-month research fellowship, joining this department in January 2017. 

Please see my personal webpage for further information.

 

Research | Current

I develop statistical methods and software to estimate ecological parameters of interest, usually animal abundance or density. My recent work has met statistical challenges that arise when instruments like microphones, video-cameras, and drones are deployed to detect animals on wildlife surveys. New technologies have the potential to collect mountains of data at a low cost, but complicate estimation of ecological parameters because less information is encoded within each detection. For example, we can easily identify an individual on a live-trapping survey via a securely fixed ID tag, but perhaps cannot do so from a fleeting glimpse in a video.

I have additional research interests in spatial point processes, statistical computing, and applied statistics in general. My work in these areas sometimes overlaps with ecology, but has also led to publications in the fields of medicine and veterinary science.
