BSc W.Aust., PhD W.Aust.
Research in biological nitrogen fixation, especially the biology of the root nodule bacteria (Rhizobium, Bradyrhizobium, Sinorhizobium.). Specific projects currently funded by external research grants (Australian Research Council, Grains Research and Development Corporation) include:
a) iron nutrition and siderophore production in Rhizobium leguminosarum by viciae
b) molecular biology of acid tolerance genes in Sinorhizobium medicae
c) physiology of acid tolerance in Rhizobium and Sinorhizobium
d) selection of improved rhizobial inoculants for crop and pasture legumes
