My broad research interests are in the genetics of grain compostion, and how this can be understood and improved for the different end uses of the grain.

My current research is on the identification, validation and understanding of interactions between genes influencing the different polysaccharides within the plant cell walls using a range of contemporary genetic techniques, in particular but not exclusively in barley. I have strong links to the Australian Research Council Centre of Excellence in Plant Cell Walls, University of Adelaide and La Trobe University, and currently collaborate on multiple projects, including shared supervision of postgraduate students, with these groups. Most of this work is focused on gaining a better understanding of the regulation of (1,3;1,4)-beta-glucan synthesis in the grasses, and in particular the role of the cellulose synthase like (Csl) genes in barley.  (1,3;1,4)-beta-glucan in the grain is of notable interest as this polysaccharide has been shown to be beneficial for human health but detrimental to the brewing and distilling industry.

Barley grain contains a range of micronutrients, some of which can have a detrimental impact on the plant/ human health. Identfiying genes that influence the grain content of these micrnutrients can therefore be beneficial.

Additionally I am interested in the genetics underlying the flavour component provided by malted barley, and if different cultivars provide different flavour profiles.
