I am an interdisciplinary scientist with a focus on coastal and marine ecosystems. Based in North Queensland, I have been working across the tropical Indo-Pacific for 10 years. I am currently a lecturer and research scientist with the College of Science and Engineering at James Cook University. My research seeks to understand how seagrass and seaweed meadows, mangroves forests, coral reefs, rivers, estuaries and wetlands underpin fish populations, fisheries and human communities. I am interested in how landscapes, including human landscapes, function as ecosystems in different parts of the world. I am focused on providing relevant, context specific and data-rich science for the management of these ecosystems, by harnessing recent innovations such as Artificial Intelligence. I also develop phone apps to allow for the widespread collection of critical new data, such as fish catch from remote communities in the Pacific, and shark-human interaction in Queensland fisheries.

How are stingray communities distributed across tropical intertidal sandflats and which environmental factors influence their habitat use?
- Indicative Funding
- $11,665 over 3 years
- Summary
- Stingrays are important meso-predators in coastal habitats around the world that impact biotic communities and structure physical environments. However, broad spatial assessments of ray habitat use are lacking, resulting in poor understanding of their ecological value and how to implement effective management strategies. The project aims to assess how the composition of stingray communities varies across tropical intertidal sandflats and which environmental variables (including prey availability) influence their distribution patterns. This goal is divided into five research objectives whose outcomes will improve habitat use models for intertidal rays and investigate important aspects of ray foraging and movement behaviours.

Integrating spatio-temporal distributions of estuary whiprays (Hemitrygon fluviorum) with natural behaviours to better understand fine-scale habitat use in estuary environments
- Indicative Funding
- $1,000 over 1 year
- Summary
- The aim of this project is to evaluate spatio-temporal distributions and behaviours of estuary stingrays to contribute new knowledge on fine-scale habitat use. Interpreting these data together will show how individuals distribute over available habitat but also which behaviours drive these patterns. Additionally, prolonged observations of natural behaviours will highlight the foraging strategies of estuary stingrays and if there are foraging facilitation interactions between rays and other fish. This component will be valuable for highlighting how data on animal behaviour can be adapted into species management.

Acoustic tagging of stingrays
- Indicative Funding
- $3,000 over 1 year
- Summary
- My aim is to assess how the dispersal and habitat selection of juvenile rays to better estimate their ecological roles and improve conservation strategies for species in tropical estuaries. Juvenile rays of two species (Mangrove whipray (Urogymnus granulatus) and Australian whipray (Himantura australis)) will be tagged and monitored over a period of 6-12 months with a passive acoustic receiver array in Deluge Inlet, QLD. This project will detail the seasonal residency, dispersal ranges, and core habitat ranges of each species over short (diel) and long-term (monthly, seasonally) temporal scales.

Distributions and behaviours of stingrays
- Indicative Funding
- $3,000 over 1 year
- Summary
- Stingrays are abundant intermediate predators in shallow coastal waters that impact biotic communities and structure physical environments. However, assessments of ray communities and their habitat use are sparse, resulting in poor understanding of their ecological value and management. For this project, I will evaluate ray populations in diverse intertidal habitats around Orpheus Island and examine how spatio-temporal factors influence community composition, distribution and behaviours. This goal is divided into research objectives with outcomes that will improve our ability to identify valuable areas for rays and understand how behaviours are linked to habitat choice, functional roles, and ecological impacts.

Addressing urgent welfare concerns for Blackspotted Croaker (Protonibea diacanthus) populations in Queensland
- Indicative Funding
- $50,000 over 3 years
- Summary
- The Blackspotted Croaker (also known as black jewfish) is targeted by commercial, recreational, indigenous and charter fishing groups. Since 2017 there has been a rapid increase in targeted commercial fishing effort for Blackspotteed Croaker in Queensland. Given the high value of Blackspotteed Croaker, their vulnerability as aggregating species and the absence of a stock assessment to inform how many populations need to be managed, updated biological/ecological information (Including stock structure) are needed for assessment and protection of Blackspotted Croaker stock(s) in Queensland. The study aims at identifying stock structure and connectivity (including aggregation time) in order to improve management of th species across Queensland.

JCU Spawning Potential app development
- Indicative Funding
- $37,500 (administered by World Wide Fund for Nature Australia)
- Summary
- The central biological measure of success for the ?Community- Based Sustainable Development in Solomon Island and PNG Coastal Communities? projects are trends in the Spawning Potential Ratio (SPR) of key target species. This Project seeks to refine the Spawning Potential Survey (SPS) App (JCU FISH) to include spatial reporting tools that can be utilised by survey participants to monitor spatial and temporal trends in SPR. This project extends from an earlier ?proof of concept? project funded by the WWF Ocean Practice where the potential for automatic identification and measurement of target species from a single image was realised.

- Indicative Funding
- $6,750
- Summary
