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 worked within two groups of ecosystems: Aotearoa’s globally distinctive peat wetlands; and our intensively managed agricultural systems. In the past few years, my research has focused on GHG emissions from drained peatlands used for agriculture. Our research group is currently advising Government ministries on improvements to the Aotearoa greenhouse gas inventory methods for organic soils.
