Yeast metabolism, low-alcohol yeast, flocculation, Brettanomyces.
Main research interests are to understand yeast metabolic networks and the interaction between gene expression, protein levels and metabolite concentrations. Expertise includes areas such as Microbiology, Bioprocess Engineering and Systems Biology. Research experience in Chile, South Africa, France and Australia.
