My PhD research involved the use of genomic tools to explore the diet, microbiome, and distribution of aquatic predators in north-western Australia. The focus species of this research included freshwater sawfish (Pristis pristis), green sawfish (P. zijsron), freshwater crocodiles (Crocodylus johnstoni), bottlenose wedgefish (Rhynchobatus australiae), giant shovelnose ray (Glaucostegus typus), and bull shark (Carcharhinus leucas). This research discovered novel trophic interactions and expanded the known diet of critically endangered elasmobranchs, examined how the microbiome of marine elasmobranchs appears to play important roles in host osmoregulation, and described the distribution of P. pristis in the Kimberley Region of Western Australia.
Additionally, I have worked as a researcher exploring how flows and inundation levels affect the abundance and diversity of zooplankton in the Lower River Murray. This research aimed to uncover the ecological impacts of water management practices on aquatic ecosystems, offering insights into sustainable management practices.
I completed my Bachelor's degree with Honours in 2020, focusing on dendrochronology and modelling carbon accumulation in Blue Pine (Pinus wallichiana) across the Bhutanese Himalayas. This work contributed to informing strategies in forest management, carbon budgeting, and climate change mitigation.
