Biography

I am a doctoral researcher in statistics and computer science at the University of St Andrews, funded by a Scholarship from the Carnegie Trust.

In 2016, I graduated from the University of St Andrews with a first class master's degree in pure mathematics. My current research, supervised by Professor David Borchers and Dr Juan Ye, seeks to exploit machine learning techniques to enable individual identification in acoustic data. An ecological application of this research is the improvement of acoustic spatial capture-recapture methods.

A short CV is available here.
