We are investigating aspects of carbon acquisition by plants including the biochemistry of CO2 fixation and regulation of CO2 diffusion into and within leaves.
We are members of two international research consortia: RIPE (Routes to Improving Photosynthetic Efficiency), an international collaboration which is aiming to improve C3 photosynthesis (https://ripe.illinois.edu/) and the C4 rice consortium which is attempting to transfer the CO2 assimilation apparatus of high yielding crops such as maize into rice (https://c4rice.com/)
Current research topics include:
- Understanding the biochemical regulation of C3 and C4 photosynthesis
- Studies on how to enhance C3 and C4 photosynthesis through molecular engineering
- Understanding CO2 diffusion inside leaves.
- Physiological and molecular regulation of stomatal movement.
