I am a botanical epidemiologist and ecologist specialising in multivariate statistics, network analysis, geographic information systems (GIS) and simulation modeling. Currently I lead the summer crops pathology theme in the Centre for Crop Health at the University of Southern Queensland researching integrated disease management of broadacre crops.
Along with Emerson Del Ponte, I co-founded Open Plant Pathology, a community of modellers and computational researchers involved in plant pathology, plant disease epidemiology, pathogen population biology, microbial ecology and genomics, that supports the several forms of Open Science practices in Plant Pathology.

Integrated Disease Management (IDM) using various combinations of cultural, fungicide and resistance strategies offer the most viable long-term option for controlling the significant field crop diseases in the Northern Region. This project aims to build on the advances in IDM of major summer and winter crops made in the GRDC-funded project DAQ00154.
Soil-borne diseases cause significant and often unexpected yield losses in broadacre crops. Annual potential national losses in wheat from soil and stubble-borne pathogens have recently been estimated to exceed $1,060 million and $792 million, respectively. Most decisions to minimise the risk from soil-borne disease need to be made before seeding, but determining which diseases pose the greatest risk can be difficult, as pathogen levels respond to changes in climate variability, farm practices, cropping sequence and crop varieties. This project provides new tools to help growers reduce the losses due to soil borne diseases.
Models will be developed using up-to-date research findings and the best scientific procedures. Before the models are applied they will be tested with location-specific data. After testing they will be used to make decision-aiding tools to assist with farm management. The decision tools will be field tested with groups of potential users across the country.
This project will result in improved decision making for management of disease in cropping resulting in improved profitability and reduced financial risk for Australian grain growers.
This project conducted two studies in 2015 and 2016 at IRRI to understand the effects of alternate wetting and drying water saving technologies on rice sheath blight.
This project is evaluating the potential environmental impact of rice production in North Queensland along with fertiliser practices that optimise yield while minimising environmental losses.
