Understanding an exotic disease: Initiation of sex and infection by the sugarcane smut Ustilago scitaminea. Australian sugar exports generate almost $2 billion in annual sales, making the sugar industry a critical facet of the Australian economy. In 2006, Australia's primary sugar producing region came under threat when an outbreak of sugarcane smut caused by the fungus Ustilago scitaminea first appeared in Queensland.

Australian sugar exports generate almost $2 billion in annual sales, making the sugar industry a critical facet of the Australian economy. In 2006, Australia's primary sugar producing region came under threat when an outbreak of sugarcane smut caused by the fungus Ustilago scitaminea first appeared in Queensland. Management of this potentially devastating disease has focused on breeding programmes aimed at developing resistant sugarcane cultivars, a complex process hampered by a lack of information about the mechanisms of smut resistance. Our research will provide key insight into the mechanisms by which U. scitaminea infects sugarcane, directing future breeding efforts and protecting this valuable industry against further outbreaks.Read moreRead less
Epidemiology and pathogenesis of chytridiomycosis in Australian frogs. Strong evidence exists that chytridiomycosis is an introduced disease of amphibians that has caused mass mortality resulting in amphibian population declines and extinctions. Epidemiologic studies will include i) field and experimental studies to determine mortality rates, transmission rates, differences in species susceptibility, and persistence of the pathogen as a saprobe, and ii) molecular epidemiology of fungal strains t ....Epidemiology and pathogenesis of chytridiomycosis in Australian frogs. Strong evidence exists that chytridiomycosis is an introduced disease of amphibians that has caused mass mortality resulting in amphibian population declines and extinctions. Epidemiologic studies will include i) field and experimental studies to determine mortality rates, transmission rates, differences in species susceptibility, and persistence of the pathogen as a saprobe, and ii) molecular epidemiology of fungal strains to examine spread and origin. Pathogenicity studies will be aimed at how chytridiomycosis causes death in frogs. The results will be significant for the conservation of amphibians worldwide and in improving our understanding of diseases in free-living animals.Read moreRead less
My enemy’s enemy is my friend: The genetics of major plant pathogen killers. Fungi are devastating agents of crop diseases. These plant pathogens, in turn, are often parasitized by other fungi in the field. The project will focus on such interactions between powdery mildews, important pathogens of many crops and wild plants, and their common fungal parasites (Ampelomyces spp.) that have already been utilised as
biocontrol agents in crop protection. Genetic and genomic tools will be used to deter ....My enemy’s enemy is my friend: The genetics of major plant pathogen killers. Fungi are devastating agents of crop diseases. These plant pathogens, in turn, are often parasitized by other fungi in the field. The project will focus on such interactions between powdery mildews, important pathogens of many crops and wild plants, and their common fungal parasites (Ampelomyces spp.) that have already been utilised as
biocontrol agents in crop protection. Genetic and genomic tools will be used to determine if these parasites evolved by switching host from plants to plant pathogens. The project has the potential to make a ground-breaking discovery in this field, and also establish the starting point for new innovative methods to protect a wide diversity
of crops using these fungi or specific compounds derived from them.Read moreRead less
Novel collision experiments with metastable neon atoms in an atom trap. The aim of this project is to investigate collisions involving atoms in long lived excited states (metastable states). The project will utilise a magneto-optical trap to investigate electron-atom collisions as well as interatomic collisions for ultra-cold atoms.
