Prospective research students I am happy to consider applications for PhD study from high quality applicants with existing funding, or those intending to apply for an external scholarship, in areas which correspond to my fields of expertise, described below. Please contact me via email. Any funded studentships or postdoctoral research positions that become available will be advertised on jobs.ac.uk, findaphd.com or the School of Engineering`s webpages.

Current Interests Currently, my group is undertaking work in a number of areas of civil and environmental engineering. I am particularly interested in four general areas:

Interactions between geoenvironmental 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.
Biological and chemical energy storage in the ground. We are using microbial fuel cells and in-ground fuel generation and supply to explore energy storage and extraction from soils and sediments.
Contaminated land remediation, particularly engineering aspects of technologies involving electricity and biology. 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. We are using electrokinetic techniques for the remediation of metal- and organic-contaminated ground.
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.

Current interests

Currently, my group is undertaking work in a number of areas of civil and environmental engineering. I am particularly interested in four general areas:

Interactions between geoenvironmental 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.
Biological and chemical energy storage in the ground. We are using microbial fuel cells and in-ground fuel generation and supply to explore energy storage and extraction from soils and sediments.
Contaminated land remediation, particularly engineering aspects of technologies involving electricity and biology. 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. We are using electrokinetic techniques for the remediation of metal- and organic-contaminated ground.
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.

I am a Fellow of the Higher Education Academy. My current teaching is as follows:

Materials & Construction (1st year)

Professional Studies & Construction (2nd year)

Environmental Geotechnics (3rd year)

Environmental Geotechnics (MSc)

Major projects (3rd year)

Case study & dissertation (MSc)

I have been a lecturer and now senior lecturer in geoenvironmental engineering at Cardiff University School of Engineering since September 2006. Following a Masters in Engineering at Oxford University, I joined Fugro Limited (UK), working on offshore and onshore site investigation and engineering. I then returned to Oxford University as a doctoral student working with the NERC Centre for Ecology and Hydrology (Oxford). Postdoctoral work at Cambridge University Engineering Department followed, with the SUBR:IM (Sustainable Urban Brownfield Regeneration: Integrated Management) consortium. Whilst in Cambridge, I was elected Fellow of Robinson College.
