Research Interests

My research contributes to the understanding of how ecosystems function, especially the way they exchange water, energy, carbon, and greenhouse gases with their atmospheric environment. I have predominantly worked within two groups of ecosystems: N.Z.’s globally distinctive peat wetlands; and our intensively managed agricultural systems. In the 1990’s I was an early adopter of micrometeorological methods for investigating the water and energy balances, then CO2 and CH4 exchanges, of wetlands. With colleagues, I then applied these methodologies to investigate whole-farm carbon balances as a way of understanding the impact of the intensive management of grazed farming systems on soil carbon stocks. We now use these approaches to study ecosystem-scale greenhouse gas exchanges while still focussing on the sensitivity of ecosystems (whether natural or managed) to disturbance regimes, climate extremes (e.g. drought), and environmental change.
