About

My primary area of research is the application of geospatial technologies (e.g., Geographic Information Systems and remote sensing) to the study of Earth’s environment and natural processes. I am particularly interested in coral reef processes and geomorphology.

I first developed an interest in coral reef geomorphology (how reef features form and evolve) during my undergraduate degree at James Cook University where my honours research examined the impacts of harbour infrastructure on reef islands in the Torres Strait. I later completed a Masters in Geospatial Technologies in Europe with a particular focus on spatial data interoperability. After a few years working as a spatial analyst in the environmental consultancy industry I decided to return to coral reef research and completed a PhD at The University of Sydney. I enjoy multidisciplinary research and the opportunity to combine field work with a variety of geospatial technologies to better understand the world and our part in it.

Current Funding

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

Great Barrier Reef Foundation - Reef Trust Partnership

Sea cucumber monitoring project

Indicative Funding: $37,969 over 3 years (administered by Macquarie University)
Summary: Although we know that sea cucumbers play an important role in bioturbation on coral reefs, there are still many unknowns in terms of the ecosystem services that they provide. Additionally, their spatial and temporal density and distribution throughout the Great Barrier Reef World Heritage Area is not well understood, yet we continue to harvest individuals to support global fisheries. We therefore need accurate baseline data of the sea cucumber populations, otherwise our extractive industries will remain at odds with ecosystem management goals. Achieving a comprehensive understanding of these populations will require a multiscaled approach incorporating intensive in situ surveys, collating industry and anecdotal observations, modelling habitat suitability, and broader scale surveys with remote sensing.

Great Barrier Reef Foundation - Reef Trust Partnership

GBRF EOI Island Monitoring

Indicative Funding: $397,435 over 2 years (administered by Department of Environment and Science)
Summary: The more than 1000 islands and cays in the Great Barrier Reef (GBR) World Heritage Area (GBRMPA spatial data, 2019) support a diverse range of ecological, cultural and economic values. Many are threatened by climate change, but monitoring and management is difficult as many cays are remote and difficult to access. This project will develop and implement an efficient drone-based hierarchical monitoring protocol based on the recognition and use of `natural ground control points? that will enable more rapid and resource efficient capture of reef island status to inform management decisions.
Investigators: Scott Smithers, Stephanie Duce, Karen Joyce, Nicholas Murray and Jack Koci (College of Science & Engineering)

Australian Centre for International Agricultural Research - Fisheries Program - Small Research Activity

Spatially integrated Portfolio Approach to support livelihoods

Indicative Funding: $248,458 over 2 years
Summary: The Integrated Livelihoods Approach (ILA) provides an approach to diagnose and help navigate interrelated and cumulative impacts, trade-offs and co-benefits of interacting livelihood activities occurring in spatially defined coastal areas. Participatory and interdisciplinary research, integrated governance, negotiation, trust-building, ongoing conflict management, and cross-sectoral and political engagement are central to the ILA. This project will establish the mechanisms for achieving the strengthened networks, integrated governance and policy, and improved planning required to implement an ILA in Western Province, Solomon Islands, with the potential to scale-up to other locations.
Investigators: Amy Diedrich, Jacqueline Lau, Tiffany Morrison, Nicholas Murray, Stephanie Duce, Claire Holland, Faye Siota and Bethany Smith (College of Science & Engineering, ARC Centre of Excellence for Coral Reef Studies, College of Business, Law & Governance and WorldFish Solomon Islands)

Eco Logical Australia Pty Ltd - Research Grant

Green turtle satellite tracking data analysis and reporting

Indicative Funding: $60,000 over 2 years
Summary: The project aims to understand (2) the patterns of habitat use and home range of foraging green turtles in Port Curtis? (2) How green turtles use habitats located within and immediately adjacent to port infrastructure in the western and southern sections of the Port, such as jetties and navigation channels? And (3) What are the patterns of movement and foraging behaviour of green turtles that shift between inside and outside the Inner Port habitats (i.e. from Pelican Banks to offshore of Curtis Is)?
Investigators: Mark Hamann, Emily Webster and Stephanie Duce in collaboration with Colin Limpus and Takahiro Shimada (College of Science & Engineering, QLD Department of Environment and Heritage Protection and Australian Institute of Marine Science)

CRC for Developing Northern Australia Scheme - Projects

Applying new technologies to enhance biosecurity and cattle quality.

Indicative Funding: $1,084,500 over 3 years (administered by Branir Pty Ltd & Trustee for Booloomani Unit Trust)
Summary: The vast natural environment of Northern Australia feeds the cattle industry; however, biosecurity threats have negatively impacted this. Conventional management of such threats such as weeds are not suited to such broad, harsh landscapes. The project will use an Internet of Things network with low-cost environmental sensors, drone mapping and big data analytics to develop and test data-driven, strategic pest management programs - ultimately improving both cattle industry and natural assets.
