Biography

I am Emeritus Professor of Soil Ecology at University of Nottingham, where from 2014-2020 I was Professor of Soil Biology. I graduated in Agricultural Botany from the University of Reading in 1981, and completed a PhD in grassland ecology at the University of Bristol in 1984. I then moved to Scotland to lead research programmes at the Macaulay Institute for Soil Research and the Scottish Crop Research Institute. From 2002-14, I held a Chair in Soil Biology at Cranfield University.

I am currently joint Editor-in-Chief of the journal Soil Biology & Biochemistry

Expertise Summary

I am a soil ecologist with experience in studying a wide range of interactions between soils, plants, microbes and fauna in a variety of systems. My research interests focus on developing a mechanistic understanding the origins and functional consequences of the compositional and spatial organisation of soil communities. This work underpins the development of frameworks for understanding factors that regulate the activity of soil communities, systems to manage the biota appropriately, and incisive procedures for assessing and monitoring soil health
