Dr Michelle Walker is a Postdoctoral Research Fellow at the Waite Campus, in the Department of Wine and Food Science. Dr Walker is a member of the Wine Microbiology and Biotechnology Group, with 20+ years experience in yeast genetics and molecular biology. She is interested in understanding the genetic basis of stress tolerance and fermentation attributes of wine yeast Saccharomyces cerevisiae, and applying this knowledge in strain improvement strategies to generate new yeast strains, better suited to Australian conditions.

I am a senior Postdoctoral Research Fellow in the Wine Microbiology and Biotechnology group within the Department of Wine and Food Science at the Waite Campus. My background is in yeast genetics/molecular biology and microbiology/biochemistry. My research interests in wine Saccharomyces cerevisiae are on yeast strain improvement and deciphering the genetic basis behind improved fermentation performance and other oenological attributes, as well as understanding the cellular mechanisms behind yeast adaption and stress tolerance of wine-like conditions, which enable yeast to successfully complete alcoholic fermentation.
