Research Interests
Photosynthesis and photorespiration in higher plants are current topics of interest. Long term goals seek to understand limitations on photosynthetic carbon metabolism with a view to enhancing crop productivity. Research involves studies at the whole plant, cellular, organellar, and enzymic levels. Specific interests are:
- The regulation of the primary CO2 fixing enzyme, RuBP carboxylase/oxygenase, and
- Naturally occurring physiological and biochemical strategies adopted by certain plants to reduce the wasteful process of photorespiration.
