About

Carla Ewels is a Lecturer in statistics/data sciences at James Cook University. She received her doctoral in statistics from the Queensland University of Technology supervised by the Distinguished Professor Kerrie Mengersen. Carla has strong interests in statistical modelling and methods, particularly in the Bayeisan framework. These include, but are not limited to, modelling of complex systems, Bayesian temporal and spatial models, model comparisons, classification, clustering, analysis of big data and Markov Chain Monte Carlo methods. She is especially interested in applying statistics to real problems. To date, she has worked in the field of marine and medical research, genetics, agriculture and fisheries.

Current Funding

Current and recent Research Funding to JCU is shown by funding source and project.

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
