Dr Kari E. Dunfield is a Professor and Tier 2 Canada Research Chair in Environmental Microbiology of Agro-ecosystems in the School of Environmental Sciences at the University of Guelph, Canada. Working at the intersection of microbiology, ecology, and soil science, her work investigates the microbial communities and microbial processes driving the global processes that help support life on Earth. She is the North American Representative for the UN-FAO Global Soil Partnership (Pillar 1). Dr Dunfield is currently the Co-Editor-in-Chief of the Canadian Journal of Microbiology. Dr Paolo Nannipieri is Emeritus Professor at the University of Florence (Firenze), Italy. He has authored/co-authored around 250 publications and has edited eight books, including the 3rd edition of Modern Soil Microbiology. Dr Nannipieri is the Editor-in-Chief of Biology and Fertility of Soils and member of the Editorial Board of Arid Soil Research and Rehabilitation. He has been the International Representative of the Italian Society of Soil Science at IUSS and president of the Italian Society of Agricultural Chemistry and of the Commission Soil Biology of the IUSS. Dr Ian Lidbury is a Royal Society University Research Fellow at the University of Sheffield investigating plant-microbe interactions. He has a background in environmental nutrient cycling, microbial ecology and ecological interactions. His lab combines computational and wet-lab approaches to understand the functional role of key microbes in the environment, particularly those in agriculture. Joann K. Whalen is a James McGill Professor at McGill University and an Affiliate Professor with the African Genome Center at the Mohammed VI Polytechnic University (UM6P) in Morocco. Her research focuses on soil fertility and soil ecology in agroecosystems. She has published more than 250 peer-reviewed scientific publications and supervised/co-supervised more than 60 students at the M.Sc. and Ph.D. levels. Dr. Whalen is currently a Chief Editor for Soil Biology and Biochemistry, a Subject Editor for Applied Energy and a Review Editor for PNAS Nexus.
