My group is undertaking work in a number of fields of civil and environmental engineering. I am particularly interested in four general areas:
• Interactions between civil and geotechnical engineering and biology (‘biogeotechnics’). Many organisms, particularly plants and microorganisms, have the potential to impact on soil structure and properties. We are developing a number of projects in this area, for example in situ biofilm growth for soil stabilisation and self-healing of geotechnical structures.
• Biotechnology in contaminated land remediation. We are using living organisms, both plants and microorganisms, in a range of projects. These include dealing directly with contamination through bioremediation as well as using biological methods to enhance other techniques, particularly those that are operated in situ, such as pump and treat or electrokinetics.
• Electrical properties of soil and groundwater. We are using electrokinetic techniques for the remediation of metal- and organic-contaminated ground, as well as investigations of potential energy applications.
• Resource recovery from waste. Many waste repositories contain significant quantities of valuable elements but their recovery has been considered uneconomic or not feasible (or both). We are investigating technologies for material recovery in a range of waste types.
