Demographic and evolutionary inferences from large, whole-genome datasets. A new data structure for genome-wide datasets has allowed great improvements in the efficiency of genomic data storage and in population genomics simulations, which are crucial to developing and testing mathematical models of population history and species evolution. We will take these advances in new directions, using efficient data structures to dramatically improve inferences about: the demographic histories of populations, rates of genome change, and phylogenetic networks, and we will develop the first inference methods for the multispecies coalescent with recombination. Outcomes will include advances in understanding the evolutionary histories of humans and other species, including pathogens of importance for global health.Read moreRead less
Evolution and role of neo-sex chromosomes in mitonuclear co-evolution. This project aims to characterize the evolution of novel, extended sex chromosomes in an Australian bird, then elucidate their role in climate-associated adaptive evolution. The species falls into two lineages bearing distinct mitochondrial genomes and nuclear-encoded mitochondrial genes carried on sex chromosomes. The project aims to test whether this extraordinary genome arrangement is splitting the species into two forms: ....Evolution and role of neo-sex chromosomes in mitonuclear co-evolution. This project aims to characterize the evolution of novel, extended sex chromosomes in an Australian bird, then elucidate their role in climate-associated adaptive evolution. The species falls into two lineages bearing distinct mitochondrial genomes and nuclear-encoded mitochondrial genes carried on sex chromosomes. The project aims to test whether this extraordinary genome arrangement is splitting the species into two forms: one adapted to hotter, drier environments, one to milder ones. This would be tackled using an innovative combination of genomics, cytogenetics, and metabolic data. Understanding the mechanisms at play would represent a major advance in ecology and evolution, with potential implications for conservation management.Read moreRead less
Can mitochondrial and nuclear co-evolution drive climate adaptation? This project aims to reveal whether co-evolution between the mitochondrial genome of a wild bird and partner nuclear genes is causing the species to split into two forms, one adapted to inland environments and one to coastal conditions. Mitochondrial-nuclear co-evolution has great potential to illuminate new modes of climate adaptation and lineage divergence. This understanding will provide significant benefits, with implicatio ....Can mitochondrial and nuclear co-evolution drive climate adaptation?

Towards a superannuation system fit for the future. Towards a superannuation system fit for the future. This project aims to develop a stochastic superannuation model and propose alternative post retirement solutions, using data-led understanding of savings habits. Funding for the increasing cost of the growing older population will, if not modelled, forecast and managed adequately, swamp all other welfare and state funded costs. To manage older age costs adequately, governments need to encourag ....Towards a superannuation system fit for the future. Towards a superannuation system fit for the future. This project aims to develop a stochastic superannuation model and propose alternative post retirement solutions, using data-led understanding of savings habits. Funding for the increasing cost of the growing older population will, if not modelled, forecast and managed adequately, swamp all other welfare and state funded costs. To manage older age costs adequately, governments need to encourage people to save and provide ways people can save—but need to better understand how people save money for their old age. This research is expected to enable the “superannuation change“ necessary for the superannuation system to remain sustainable and fund retirees to live well.Read moreRead less
Alcohol and tobacco use among lesbian, bisexual and queer identifying women. This project aims to examine practices of alcohol and tobacco use among lesbian, bisexual and queer-identifying (LBQ) women, which are considerably higher compared to heterosexual women. By using an innovative, longitudinal qualitative approach, this project expects to generate new knowledge regarding the cultural and social forces that shape higher rates of alcohol and tobacco use among LBQ women, and to better underst ....Alcohol and tobacco use among lesbian, bisexual and queer identifying women. This project aims to examine practices of alcohol and tobacco use among lesbian, bisexual and queer-identifying (LBQ) women, which are considerably higher compared to heterosexual women. By using an innovative, longitudinal qualitative approach, this project expects to generate new knowledge regarding the cultural and social forces that shape higher rates of alcohol and tobacco use among LBQ women, and to better understand their impacts. It is anticipated that the project will enhance the capacity of health promotion and policy organisations to meet the alcohol management and smoking cessation needs of this population. Findings from this project should help to alleviate health and social inequalities experienced by LBQ women.

Solving the disability data puzzle to ensure progress towards equity. In South Korea, the average age of death for people with disability is 16 years younger than people without disability. In Australia, we do not have the data infrastructure to generate life expectancy statistics for people with disability. This fellowship aims to solve this disability data challenge, identified as a critical problem by the Australian Government.

In South Korea, the average age of death for people with disability is 16 years younger than people without disability. In Australia, we do not have the data infrastructure to generate life expectancy statistics for people with disability. This fellowship aims to solve this disability data challenge, identified as a critical problem by the Australian Government. It will develop a validated methodology for producing disability statistics from linked data; generate a whole population disability data resource to build capacity in disability research; and for the first time, produce life expectancy statistics for people with disability - the ultimate policy tool to monitor progress towards equity and improve the lives of disabled Australians.

Unlocking the secrets of the mitochondrion. This project aims to determine the frequency and mechanisms by which male-harming mutations (those with negative effects limited to males) accrue within the mitochondrial DNA. Theory predicts maternal inheritance of mitochondrial DNA will lead to accumulation of these mutations, but the real-world implications of this theory are unknown. Leveraging an innovative approach, this project expects to generate new knowledge into the causes of sex differences ....Unlocking the secrets of the mitochondrion. This project aims to determine the frequency and mechanisms by which male-harming mutations (those with negative effects limited to males) accrue within the mitochondrial DNA. Theory predicts maternal inheritance of mitochondrial DNA will lead to accumulation of these mutations, but the real-world implications of this theory are unknown. Leveraging an innovative approach, this project expects to generate new knowledge into the causes of sex differences in physiology and health. Expected outcomes include insights that advance understanding of fundamental biological processes, and training of students. Expected benefits include strengthening of Australia’s research capacity, by setting the research agenda in this rapidly developing field.Read moreRead less
The life-course implications of declining adolescent drinking. The project aims to identify ways to ensure that recent declines in adolescent drinking are maintained and reinforced as these cohorts age into young adulthood. It expects to generate new knowledge on the trajectories of youth drinking into young adulthood.

The project aims to identify ways to ensure that recent declines in adolescent drinking are maintained and reinforced as these cohorts age into young adulthood. It expects to generate new knowledge on the trajectories of youth drinking into young adulthood. Expected outcomes include new cross-national understandings of the predictors of heavy drinking in adulthood and an updated evidence base for the development of harm prevention policies and interventions by governments and NGOs. This should provide significant benefits to Australia via reductions in the negative health and social impacts of heavy drinking for these cohorts across their lives. Read moreRead less
Microcosm Experiments for Improved Species Distribution Models. This project aims to use a spatially-explicit experimental system based on protists (microscopic organisms) to evaluate the predictive performance of dynamic distribution models, which are a newly-emerging class of species distribution models.

This project aims to use a spatially-explicit experimental system based on protists (microscopic organisms) to evaluate the predictive performance of dynamic distribution models, which are a newly-emerging class of species distribution models. Species distribution models are a fundamental part of ecological science, and underpin a range of applications related to managing threatened and invasive species. The project is expected to provide insights into when these models are likely to work better than more traditional correlative models in non-lab environments. The experiments will inform further development of dynamic distribution models, and help determine whether dynamic distribution models can be usefully applied to species management.Read moreRead less
