BRIEF BIO: David Wardle works as the Smithsonian Professor of Forest Ecology at Nanyang Technological University in Singapore, and and also holds adjunct positions with the Swedish University of Agricultural Sciences and with the University of Canterbury and Landcare Research in New Zealand. His research explores the links between aboveground and belowground communities and their consequences for ecosystem functioning. A large proportion of this work is field based and in natural ecosystems, including in forested ecosystems around the world as well as in subarctic and alpine tundra. Current projects focus on ecosystem impacts of invasive biota; consequences of wildfire; ecological changes across successional, retrogressive and elevational gradients; aspects of island ecology; and the ecological role of forest understory vegetation.He has authored two books on aboveground-belowground linkages (published by Princeton University Press in 2002 and Oxford University Press in 2010), and around 300 peer-reviewed journal articles of which over 25 have appeared in Science and Nature. He serves or has served on several editorial boards, including for Science, Ecology, Ecology Letters and the Journal of Ecology. He has also been recognized as a highly cited scientist in every Highly Cited list released from 2006 onwards and is among the world’s 10 most cited scientists in ecology and environmental sciences. Further, he has supervised a very diverse assortment of 46 postdoctoral researchers and PhD students, most of which have actively published in major journals under his supervision (including in Nature and Science), and most of which hold positions as university faculty or as research scientists in 16 separate countries. Wardle has been the recipient of several scientific awards (most recently the 2018 Eminent Ecologist award from the Journal of Ecology) and is an elected Fellow of the Royal Society of New Zealand and a Wallenberg Scholar.
