My PhD was a multi-disciplinary project involving medical physics and statistical image processing. More specifically I investigated the supra-molecular structure of breast cancer tissue using Small-Angle X-ray Scattering. I developed algorithms which utilised the contourlet transform and machine learning to both accurate diagnose malignant pathologies as well as provide a physical understanding of the factors which lead to this accurate identification.

I have a broad range of interests in data science, computational modelling and computer vision, particularly embedded vision. That is making small smart devices that can recognise objects visually. I am also deeply committed to translating the benefits of this research to the agricultural, ecological and health sectors.
Major projects at present include:
The impact of wild dogs on the livestock industry in this country can be absolutely devastating. Negative impacts are felt across the board whether it be from an economic, mental health, stock welfare or wildlife perspective. As a member of a rural community I have seen firsthand the devastation that can occur. Researching in to how to utilise technology and data analysis techniques to improve wild dog management is a key strategic research area of mine. Specific projects include Wild Dog Alert an automated computer system to recognise wild dogs using camera traps and Electronic Shepherd a computer system designed to monitor stock welfare and detect dog attacks on stock.
The future of the internet promises smart devices which can communicate to each other and which can monitor the environment autonomously. This research projects explores the possibilities that this technology could offer farmers. Sensor node stations are placed in situ in paddocks to monitor conditions such as soil moisture content and temperature. This data is relayed wirelessly and in real-time to a central on farm computer on which very advanced geo-spatial algorithms are used to process the data across the entire farm and advise the farmer of conditions such as the optimal time to sow a crop and provide advanced warning of drought.
The threat of a biosecurity incursion into our country poses a significant risk to our primary industries (agriculture, fisheries and forestry), biodiversity and public health. A key component in protecting Australia is adequate surveillance and early detection of threats before they establish. This research program investigates the development of intelligent systems and big data analytics to enhance our capabilities in this area.
