研究领域

Currently my main research interest is the development of more phosphorus-efficient pastures and farming systems. Research projects in this area are supported by the ARC, Meat and Livestock Australia, Australian Wool Innovation and the Peel Harvey Catchment Council. Root traits that enhance plant phosphorus uptake are a focus. In my Future Fellowship I will be investigating how plants adapt to environments where the availability of phosphorus varies greatly with season. I will look at native plants that can quickly takeup large amounts of phosphorus and store it for later use without toxicity and the role of arbuscular mycorrhizal fungi in cycling phosphorus.
