My research uses ancient DNA to understand population dynamics of extinct and extant mammals across Australia with a particular focus on the Holocene. The four chapters of my PhD focus on different aspects of faunal diversity within Australia. In particular I will be looking at the following:
1. The impact of gene flow across the Bassian Isthmus on thylacine (Thylacinus cynocephalus) distribution
2. Mitochondrial phylogeography of the western quoll (Dasyurus geofforii) across southern Australia
3. Species history of two native rodent species (Pseudomys) from Wet Cave, Naracoorte.
The results from my research will help us understand the faunal landscape and historic diversity of these mammal groups during the Holocene.
During my Honours in 2018 I implemented ancient DNA techniques to recover degraded DNA from unknown museum artifacts to assess provenance in my thesis titled 'Phylogenetic Analysis of Historic Museum Samples with Unknown Origin'. I determined that 12 unknown kakapo skins were collected form the South Island of New Zealand and an unusual whaling artifact belonged to a sperm whale with the most common mitochondrial haplotype found in the Indian, Atlantic and Pacific Oceans.
