Major Research Interests
1. Identification and classification of yeast genes specifically important for the efficiency of wine fermentation; the Fermentome
- We have approached this field of study from numerous angles including:
- screening of readily available laboratory and wine yeast deletion library collections for those genes that when deleted disrupt or enhance fermentation performance. Particular genes of interest are further explored to gain an in-depth understanding of the specific roles of such genes in a fermentation context
- with the use of directed evolution to produce fermentation efficient yeast strains and subsequent genome sequence analysis to determine which genetic elements confer this phenotype.
2.Yeast cell-cell communication of over-crowding and nutrient limitation: Novel signalling systems and their impact on fermentation
- We are interested in determining if and how both known and novel signalling molecules may impact fermentation and other related yeast metabolism
