I am a senior research fellow in the ARC Research Hub for Protected Cropping (PC Hub) at La Trobe University, and scientific advisor of the recently established La Trobe University node of the NCRIS-funded Australian Plant Phenomics Network. My background is in plant molecular physiology and plant nutrition, as well as optimizing plant performance in protected cropping environments – in particular medicinal plant cultivation. My research is diverse and impactful, ranging from identifying key regulators of nutrient signalling in model species and the role of phospholipids in early drought response of cereal roots to understanding phosphate toxicity in Australian Proteaceae. This has led me to investigate how manipulation of underlying response networks may enhance crop productivity, nutritional quality and sustainability of food production. Throughout my career, I have benefited from working together with internationally renowned experts at the Leibnitz Institute of Plant Genetics and Crop Plant Research (IPK) in Germany, as well as at the Australian National University, the University of Western Australia and the La Trobe Institute for Sustainable Agriculture and Food. My work has been cited extensively, reflecting my profound contribution to the field of plant science.
