My research contributes to the understanding of how ecosystems function, especially the ways they exchange water, energy, carbon, and greenhouse gases with their atmospheric environment. I have predominantly worked within two groups of ecosystems: Aotearoa’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. Recently, I played a key role in developing a novel technique to measure nitrous oxide emissions from agricultural land at paddock scales. With my colleagues, we developed new methodologies to investigate whole-farm carbon balances under the intensive management of grazed farming systems. In the past few years, my research has focused on GHG emissions from the vast areas of Waikato's drained peatlands used for agriculture. With colleagues, we are advising Government ministries on improvements to the Aotearoa greenhouse gas inventory methods for organic soils.
