Research

There is a long standing interest in manipulating metabolism in plants to improve the production and quality of food, medicine and other consumable products. However, metabolic engineering in plants is notoriously unpredictable – really a hit or miss affair. With a focus on plant primary metabolism, I study the post-translation mechanisms that control and balance fluxes through metabolic pathways with the aim of improving our ability to accurately manipulate these important pathways.
My experimental approach combines metabolomics with enzymology. In particular enzymes are purified and studied from their native tissues to understand the post-translational modifications that control enzyme activity in vivo.
