This project aims to illuminate the role of variation in mutation rate in driving evolutionary change. Mutation rate is a core parameter in evolutionary analyses in essential applications including epidemiology, conservation and medicine, yet remains a “black box” given arbitrary universal values. This project will take a whole-of-biodiversity approach to understanding the forces shaping mutation rate, impact on evolution of biodiversity and effect on accuracy and precision of phylogenetic analyses. Using Australian case studies, the expected outcome of this project will be a greater understanding variation in mutation rate between species, providing significant benefits in developing more sophisticated and reliable phylogenetic analyses.Read moreRead less

This project aims to study how venom, nature's most powerful weapon, evolves and shapes biodiversity. Using the iconic Australian and New Guinean venomous snakes as a model, this project expects to develop a novel approach to profile venom composition from museum specimens, test competing hypotheses on the evolution of venoms, and test for the association between the evolution of venoms and the evolution of diversity in species richness and morphology. Expected outcomes include the largest venom database for any animal group and a better understanding of how venoms evolve and what role they play in earth’s biodiversity. The generated venom data has potential to be used in future studies to aid in the development of anti-venoms and drugs.Read moreRead less

This project aims to reveal the long-term trends, processes and drivers of RNA virus diversity and evolution. Through the metagenomic sequencing of the viromes of Australian animals that mark evolutionary innovations and transitions this project will reshape our knowledge of virus evolution and disease emergence. Expected outcomes will be a new understanding of how virus diversity is created, how virus phenotypes have changed through time, how often viruses jump to new host species, and how major events in animal evolution have shaped virus diversity. Key benefits include new measures of the viral burden faced by Australia’s native animals and of ecosystem health.Read moreRead less

This project aims to locate hotspots of diversity in Australia’s vast, flat deserts and to quantify how well these areas are captured under the National Reserve System. I will establish a network of international and national collaborators and improve knowledge on how animals responded to past environmental change. The anticipated outcome of this project is to improve our ability to understand, measure and preserve our unique desert biodiversity and the evolutionary processes that sustain it, using our remarkably diverse reptile fauna as a model system. In the face of current, rapid environmental change, this has never been more important, and will provide a tool for biodiversity survival.Read moreRead less
