Research

Research Overview

I am a Soil Physicist working on solutions to food and environmental security, mainly focussed on the interactions between plants, microorganisms and the physical behaviour of soil. My work spans from understanding the fundamental processes driving changes in soil physical properties by biology, through to applied research examining soil degradation and the underlying causes.  Recent and current projects study the capacity of different plant root traits to physically engineer soil, crop selection impact on hydrological cycling in southern China, the use of vegetation to mechanically stabilise engineered slopes, soil physical impacts on nitrogen fertiliser use efficiency in Brazil and the better use of organic resources in Ethiopia to improve soils and their capacity to produce food. This research is funded by a number of research councils.

Research Specialisms

  • Soil Science
  • Environmental Sciences
  • Agriculture
  • Sustainable Agriculture and Landscape Development
  • Biophysical Science

Our research specialisms are based on the Higher Education Classification of Subjects (HECoS) which is HESA open data, published under the Creative Commons Attribution 4.0 International licence.

Current Research

My current research has four main areas: (1) engineering of the soil physical environment by plant roots, (2) impact of soil physical conditions on microbial processes, pollutant transport and root growth, (3) biophysical resilience of soil to stresses and (4) management of soil physical conditions for crop productivity.  It is underpinned by a cross-disciplinary team of staff and collaborators that includes plant scientists, soil biologists, geotechnical engineers, chemists and hydrologists.  The research uses a range of approaches including micron scale non-invasive imaging up to larger scale critical zone observatories.

Supervision

My current supervision areas are: Biological and Environmental Sciences.

A team of PhD students in the Soil Biophysics Group explores a diverse array of topics on physical and biological interactions in soil.  Graduates have research positions around the world in universities and research institutes.

The PhD students are truly multidisciplinary, made possible by diverse supervisory teams from different schools, universities and institutions.

Teaching

Programmes

  • Postgraduate, 3 stage, September start

    We offer the only dedicated soil science degree in the UK and one of the few remaining in Europe.  Soils have risen markedly on political agendas because they are central to climate change and food security.  The decades long legacy of work in this area provides comprehensive and cutting edge teaching.
