Current Research Interests:
- The potential for agriculture in developed and developing countries to adapt to climate variability and change
- The role of scale in understanding the vulnerability of complex systems, especially agro-ecosystems, to environmental change
- How land use change may influence the uptake and release of carbon in the terrestrial biosphere
- The use of experimental long-term climate forecasts to assist decision making under conditions of uncertainty
- The development of methodologies for detecting the impacts of observed 20th century climate change on natural and managed ecosystems
