Research Interests

I am a Soil Physicist who works across disciplines to understand how biological and chemical processs interact with soil physical structure and transport properties.

Roots, fauna and microbes have considerable impact on the physical properties of soil.  I use approaches from soil physics, materials science and engineering to quantify mechanical and hydrological processes that underlie the physical engineering of soil by biology. This knowledge is applied to investigate the impact of root traits on soil physical behaviour, the sustainability of agricultural production processes and the resilience of soil to external stresses.

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.
