Research interests

My research combines biochemistry with molecular biology and genomics, to solve problems in cellular processes in plants. Our focus is on mitochondrial electron transport and its associated carbon and nitrogen metabolism, and nutrient transport across symbiotic membranes in nitrogen fixing legumes.
