CSIRO - Al for Missions Postgraduate Program

AI/ML-based risk prediction for zoonotic spillover

Indicative Funding: $164,250 over 3 years
Summary: More than 70 per cent of emerging infectious diseases are transmitted from animals to humans, and their incidence has tripled over the past 50 years. Predicting future spillover risks are increasingly crucial to human health and wellbeing, and economic stability. This project focuses on developing computationally efficient AI/ML algorithms to leverage large spatiotemporal environmental, human, and animal data sets for the purpose of predicting spillover risk. The main objectives of this project are to identify ? key reservoir hosts that increase the chance of zoonotic spillovers, ? the pathogens that are most likely to emerge, ? geographic origins of a potential future pandemic, and ? use process-based approaches to supplement and help correct biases of the data-based AI/ML approaches. We expect these models and results to contribute to the early warning and decision support systems on our paths to impact.

Australian Research Council - Linkage - Industrial Transformation Research Hubs

ARC Research Hub for Supercharging Tropical Aquaculture Through Genetic Solutions

Indicative Funding: $4,996,503 over 4 years, in partnership with Australian Genome Research Facility ($150,000); Cygnet Bay Pearls PL ($500,000); Mainstream Aquaculture ($500,000); Sea Forest Pty Ltd ($500,000) and THE COMPANY ONE PTY LTD ($500,000)
Summary: This project aims to integrate cutting edge genetic and genomic approaches into innovative aquaculture enterprises that farm in tropical northern Australia. It will deliver the requisite genetic knowledge to instigate world-leading and highly productive breeding programs for five species (barramundi, pearl oyster, prawn, grouper and marine seaweed), along with a novel understanding of the genetic basis of disease resistance and how the production environment interfaces with the bacterial microbiome, pathogens and water quality to cause disease. It will increase Australia's capacity to deliver advanced genetics outcomes to the aquaculture sector, while increasing productivity, international competitiveness, and lowered risk due to disease.

Great Barrier Reef Foundation - Crown-of-Thorns Control Innovation Program (CCIP)

Empirical decision support

Indicative Funding: $147,000 over 4 years
Summary: Innovation program on CoTS control in the GBR. I am involved in the subject program, empirical decision support. In this part of program, our goal is to deliver immediate and ongoing decision support using available data, this includes analysing program data to enhance the efficiency of on water operation and the development of a new early warning system that leverages data from field and modelled data.

Great Barrier Reef Foundation - Crown-of-Thorns Control Innovation Program (CCIP)

Crown-of-thorns starfish control innovation program ? Feasibility and Design Phase (Phase 1)

Indicative Funding: $346,700 over 1 year
Summary: Recognising that manual control of COTS during outbreaks is not, on its own, an ideal long-term solution, new efforts were launched in 2016 to develop an Integrated Pest Management approach for COTS (as part of the National Environmental Science Program), led by CSIRO and involving numerous partners. This approach relies on understanding COTS distribution, movement and population dynamics, targeting critical locations and exploring new and more effective control methods. This involves both improving the efficiency and effectiveness of the current methods while also focusing efforts to better understand and manage the pre-conditioning and initiation of outbreaks. A Feasibility and Design Phase (Phase 1) is focused on assessing the feasibility (technical, social and regulatory) and modelling the benefit (impact) at scale of a broad range of possible improvements and interventions. Applying a transparent and consistent scientific framework, this Phase will lead to recommendations on priority areas that should be further investigated and developed
