Her research extends from agroecosystems to 17 seasons in the Antarctic Dry Valleys examining how global changes impact soil biodiversity, ecosystem processes and ecosystem services. She chaired the SCOPE Committee on Soil and Sediment Biodiversity and Ecosystem Functioning and edited “Sustaining Biodiversity and Ecosystem Services in Soils and Sediments (Island Press, 2004). Diana chaired the DIVERSITAS-International Biodiversity Observation Year-2001- 2002 and the Global Litter Decomposition Experiment; and co-chaired the Millennium Development Goals Committee of the Millennium Ecosystem Assessment.
