PhD student supervised by Assoc Prof. Emma Sherratt, Dr Liz Reed, and Dr Mark Hutchinson. My research focuses on how frog communities in the Naracoorte Caves World Heritage Area have changed over the last 60,000 years, and whether observed patterns reflect genuine ecological change or are artefacts of taxonomic and taphonomic biases. To taxonomically assign these fossils, I use geometric morphometrics to analyse their shape and compare them with comparative datasets quantitatively.
Interests: Allometry; Evolution; Frogs; Geometric Morphometrics; Palaeontology; Palaeobiology; Palaeoecology; Taphonomy
