Mobility project

Yeasts associated with Drosophila in winegrowing environments

This project examines the distribution and composition of yeast communities associated with the wine growing area of Languedoc-Roussillon and particularly those associated with Drosophila insects. A modified pyrosequencing database will be produced to accurately assign yeast species. Comprehensive sampling will give information about the composition of yeast species in vineyards. Yeast distribution and diversity will be captured by this project, and will assist in delimiting geographic areas of wine production. The microbial consortia of the emerging pest, Drosophila suzukii will be a particular focus.

Biography & research interests

I completed my PhD in wine microbiology and molecular biology at the University of New South Wales and the Australian Wine Research Institute in 2005. I conducted postdoctoral training at the University of Geneva in the laboratory of Professor Howard Riezman, with elements of this research communicated in a well-regarded Science publication. Upon my return to Australia in 2007, I was appointed to a competitive academic tenure-track position at the University of Melbourne, which is considered Australia’s leading higher education and research institution. My research now considers microbial and insect ecology in agricultural systems, which is very applicable for study in the well-established and regarded wine regions in France. I am excited to concentrate on research and communication in an intensive laboratory environment in Montpellier in 2015. My medium career goal is to be a well-regarded researcher in wine and agriculture, attracting competitive funding and communicating in quality journals. For my longer-term goals, I aim to become a professor and head of a motivated and committed laboratory. Developing international networks and linkages through this fellowship will provide critical support for me to achieve this aim.
