Welcome to Dave Johnson

Welcome to Professor Dave Johnson who has joined the School this month. Dave has taken up an N8 Chair in Soil Microbial Ecology, and was previously at the University of Aberdeen. Dave will also be joined by new research staff later in the month.

Dave is a terrestrial ecologist with a particular interest in understanding how plants interact with the myriad organisms that live in soil, especially symbiotic mycorrhizal fungi, and the consequences of these interactions for biogeochemical cycles. His research falls under three main areas: i) how components of biodiversity (functional groups, species and genotype) regulate ecosystem functions such as greenhouse gas production and nutrient cycling, ii) the ecological and evolutionary implications of multi-trophic interactions, including those mediated below ground by mycorrhizal fungal networks, and above ground via vertebrate and invertebrate herbivores and seabirds, and iii) impacts of land-use, climate and environmental change on ecosystem processes. His work cuts across several scales, from genotypes to communities, and involves working in a diversity of environments to answer particular questions. For example, current research is concerned with tropical forests, boreal forest, extensive and intensive grassland, and cropping systems. To address many of his research questions, he uses radio and stable isotope tracers both in the laboratory and the field, and take a reductionist approach to manipulate critical components of biodiversity. Much of his research is supported by grants from NERC and BBSRC.
