My research seeks to understand the environmental and biological controls on carbon dioxide and water vapour exchange between plants and the atmosphere. I use a range of measurement techniques to gain a deeper insight into these processes, including measurements of how the stable isotope compositions of carbon dioxide and water vapour change during photosynthesis and transpiration. I am also interested in improving the interpretation of stable isotope signals in plant organic material, in order to gain insight into how leaf gas exchange has responded to global climate change through time and space. I am especially interested using these tools to understand how tropical rainforests are responding to climate change, and what role they are likely to play in modulating the response of the global carbon cycle to human activity in the coming century. I am currently a senior lecturer at James Cook University- Cairns. I am looking for students to join my lab, so if you are interested in discussing a research project, please do get in touch.

Unsaturation of vapour pressure inside leaves: fundamental, but unknown
- Indicative Funding
- $511,100 over 3 years
- This project will determine when and to what extent the air inside leaves becomes unsaturated with water vapour. All current interpretation and modelling of leaf gas exchange assumes saturation under all circumstances. Compelling evidence has been obtained suggesting this is not true under moderate air vapour pressure deficits. A novel technique will be employed to assess the water vapour concentration of the air inside leaves based on stable isotope analysis of carbon dioxide and water vapour exchanged between leaves and air. The project will provide fundamental knowledge about how stomata regulate photosynthesis and water use, with significant implications for modelling vegetation function and for improving the performance of crop plants.

Oxygen isotope (?18O) composition of leaves and wood in rainforest plants grown under varying environmental conditions
- Indicative Funding
- This project aims to identify environmental factors (such as varying altitudes, humidity, temperature, rainfall and carbon dioxide concentrations) that change the stable oxygen isotopic ratio within the wood and leaves of rainforest plants. This will be done through analysis of samples collected from wet tropics forests, and from grown plants in controlled greenhouses (with varying temperatures and CO2 levels). The results will help to explain how plants have responded to past environmental changes, and to infer how they will respond to future changes. This will assist in the development environmental management practices of the wet tropics bioregion.

Abrasive Blasting - Are There Any Environmental Concerns
- Indicative Funding
- $105,755 over 2 years
- The re-surfacing and re-use of existing high voltage towers instead of removing and replacing with new structures has the potential to alter the way that power transmission infrastructure is used in the long term in Queensland. This project will look at using abrasive blasting in the high value and sensitive landscape of the rainforests of the Wet Tropics and will develop the science narrative around how the process interacts with the local environment.
