Areas of interest
- Risk assessment of chemicals

- Carbon turnover in soils
My research focuses on determining the factors controlling exposure of biota to environmental pollution. This work combines experimental data with process description models and development of assessment tools.
Projects have been supported by a wide range of funders across industry, government and research bodies.
Recent research focuses on the role of soil organic carbon in modifying pollutant exposure and the parallels between pollutant and carbon cycling in soils using high level analytical techniques such as mass spectrometry and nuclear magnetic resonance.
