The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Summary
How ecology shapes the viromes of wild birds. This project will reveal the host factors associated with the diversity, evolution and dynamics of viruses using state-of-the-art metatranscriptomics in Australian wild birds. The structure of virus communities and their associated ecological drivers in wild animal hosts remain a black-box, even though they are the largest source of viral diversity in nature. This project expects to generate key insights into host-associated drivers of viral communit ....How ecology shapes the viromes of wild birds. This project will reveal the host factors associated with the diversity, evolution and dynamics of viruses using state-of-the-art metatranscriptomics in Australian wild birds. The structure of virus communities and their associated ecological drivers in wild animal hosts remain a black-box, even though they are the largest source of viral diversity in nature. This project expects to generate key insights into host-associated drivers of viral community dynamics and the subsequent effect of anthropogenic factors such as urbanisation and poultry production. Identifying host factors that affect viral ecology in wild birds will constitute a cornerstone in understanding the emergence of virulent viruses and/or their spread to poultry or humansRead moreRead less

Summary
Redefining virus ecology and evolution. This project aims to employ novel genomic analyses of viruses from Australian fauna to resolve major questions in RNA virus ecology and evolution, and is expected to reveal the basic processes that shape the virosphere, determine how viruses jump species to emerge and cause disease in new hosts, and how viruses evolve new levels of virulence. The research will provide a new understanding of how viruses evolve and contribute to global ecosystems and develop ....Redefining virus ecology and evolution. This project aims to employ novel genomic analyses of viruses from Australian fauna to resolve major questions in RNA virus ecology and evolution, and is expected to reveal the basic processes that shape the virosphere, determine how viruses jump species to emerge and cause disease in new hosts, and how viruses evolve new levels of virulence. The research will provide a new understanding of how viruses evolve and contribute to global ecosystems and develop new bioinformatics tools to identify and analyse highly divergent genome sequences through studying meta-transcriptomic data from diverse animal phyla, from prokaryotes and basal eukaryotes, from iconic native mammalian species and their major invasive pests. The benefits provided will include determining the viromes of native and invasive species and enhancing the efforts to protect iconic Australian species from infectious disease.Read moreRead less
An interdisciplinary approach to host-pathogen interactions in infection. This project aims to understand the molecular and cellular interactions between host and parasite, as well as providing a quantitative framework for analysing infection dynamics in other systems. Infection involves a complex interaction between the host and the parasite, which is very dynamic and therefore difficult to study by traditional sampling and analysis approaches. This project has combined mathematical modelling w ....An interdisciplinary approach to host-pathogen interactions in infection. This project aims to understand the molecular and cellular interactions between host and parasite, as well as providing a quantitative framework for analysing infection dynamics in other systems. Infection involves a complex interaction between the host and the parasite, which is very dynamic and therefore difficult to study by traditional sampling and analysis approaches. This project has combined mathematical modelling with a novel experimental protocol to allow the study of kinetics of parasite replication in vivo. Expected outcomes will provide significant benefits, such as new avenues for vaccination and immune intervention.Read moreRead less
Antigenic analysis of the surface of Cyclospora cayetanensis oocysts. Infection with Cyclospora cayetanensis is an emerging disease that causes significant morbidity in human populations. Although prevalent in developing countries, recent outbreaks in the USA confirm it is now emerging into the developed world. The research described here will analyse and characterise the antigens on the surface of the oocyst of C. cayetanensis which will add significantly to our sparse knowledge on this impor ....Antigenic analysis of the surface of Cyclospora cayetanensis oocysts. Infection with Cyclospora cayetanensis is an emerging disease that causes significant morbidity in human populations. Although prevalent in developing countries, recent outbreaks in the USA confirm it is now emerging into the developed world. The research described here will analyse and characterise the antigens on the surface of the oocyst of C. cayetanensis which will add significantly to our sparse knowledge on this important human parasite. We will also develop the first commercial antibodies and technologies which will rapidly and accurately detect the parasite in human patients and our drinking water supplies, thus securing a global market for Australian technology.Read moreRead less
Revealing the evolutionary and ecological dynamics of avian influenza virus. This project aims to understand how avian influenza virus (AIV) emerges, evolves and spreads in wild birds. AIV has the potential to devastate the poultry industry and cause human pandemics, but the factors that shape the genetic diversity of AIV in its wild bird reservoir are poorly understood. The project plans to combine genomic, ecological and phylogenetic approaches to reveal key aspects of AIV evolution, as well a ....Revealing the evolutionary and ecological dynamics of avian influenza virus. This project aims to understand how avian influenza virus (AIV) emerges, evolves and spreads in wild birds. AIV has the potential to devastate the poultry industry and cause human pandemics, but the factors that shape the genetic diversity of AIV in its wild bird reservoir are poorly understood. The project plans to combine genomic, ecological and phylogenetic approaches to reveal key aspects of AIV evolution, as well as the risk for future viral emergence. Using sampling sites in Australia and Antarctica, it plans to investigate AIV diversity, the evolutionary dynamics of AIV in wild birds and poultry, and the role played by environmental transmission in AIV ecology.Read moreRead less
