Our research is focused on understanding the mechanism of leaf development. In particular, we are interested in the interplay of cell growth and division, how these parameters are integrated into the developmental program controlling leaf structure, and the impact the resultant internal cellular architecture has on leaf function- particularly photosynthesis and water-use efficiency. We take an integrated systems approach, using experimental data derived from advanced imaging, biochemistry and physiology to inform computational models, which we then use to develop testable hypotheses on how structure relates to function, utilising a range of genetic and experimental approaches to alter specific elements of the modelled system.
