I am an ecophysiologist broadly interested in how environmental and biological controls influence the exchange of carbon dioxide and water vapour between plants and the atmosphere. I use a range of techniques to gain deeper insight into these processes including the measurement of stable isotope compositions of carbon dioxide and water vapour, which are altered by photosynthesis and transpiration. The focus of my recent research has been to develop new methods to test the theory of 18O photosynthetic discrimination, with the aim to improve the estimation of mesophyll conductance and the saturation level of water vapour inside the leaf. Both of these plant attributes cannot directly be measured, but are important to our understanding of what limits carbon assimilation.
The aim of my work with the Physiological Plant Ecology group is to identify the key biochemical and physiological processes that determine the metabolic information recorded in the stable hydrogen composition of plant organic compounds such as leaf wax lipids, lignin and cellulose (HYDROCARB project). In doing so, I hope to contribute to the development of a new proxy for the carbon metabolism of plants that can be used to understand how plants have and are responding to climate change.
