Research interests
CO2 fixation and water loss of leaves
We are investigating aspects of carbon acquisition by plants including the biochemistry of CO 2 fixation and regulation of CO 2 diffusion into and within leaves. Current research topics include: - Studies on the biochemical regulation of C3 and C4 photosynthesis
- Physiological and molecular regulation of stomatal movement.
- CO2 diffusion inside leaves.

CO2 acquisition by cyanobacteria and plants, and impact of climate change
Projects deal with CO2 acquisition by cyanobacteria and plants, and impact of climate change, and engineering plants that use less water

Understanding the cellular and genetic basis of differences in photosynthetic leaf capacity between Arabidopsis and a close mustard relative Hirschfeldia incana.
Aim: To use comparative analysis of Arabidopsis and a closely related mustard species, Hirchfeldia incana, to gain an understanding of what determines various aspects of leaf photosynthetic capacity and its environmental plasticity.
