2017-2020: Genetic factors influencing biocontrol bacteria colonisation of plant surfaces
PhD supervisors: Professor Ian Paulsen and Dr Sasha Tetu

2016: Germination of Australian native wild cotton seeds – establishing a range of methods for germinating stubborn seeds of some wild cottons

2014-2015: Functional analysis of extrafloral nectaries of Australian native wild cottons
–  examined the morphology and anatomy of extrafloral nectaries of four species of wild cotton using light microscopy, scanning electron microscopy and histochemistry to shed light on how extrafloral nectar is produced
– analysed the composition of extrafloral nectar and phloem sap of wild cottons
– used 14CO2 labelling to investigate the fixation, storage and secretion of carbon in extrafloral nectar and calculate the carbon cost of extrafloral nectar production
– examined the response of extrafloral nectar composition and production to elevated atmospheric carbon dioxide
MRes supervisors: Professor Brian Atwell and Distinguished Professor Lesley Hughes
