My research on transport infrastructure encompasses
- in-ground construction to reduce environmental impacts in urban and other sensitive areas (retaining walls and groundwater control)
- effects of vegetation and climate on embankments and cutting slopes
I have worked on major projects including the
- A55 Conwy Crossing
- Jubilee Line extension stations at Canary Wharf and Canada Water
- Channel Tunnel Rail Link.
I am a co-author of two Construction Industry Research and Information (CIRIA) reports incorporating the results of my research in groundwater control (C515) and embedded retaining walls (C580). I currently lead TRACK21, a major EPSRC-funded research consortium with the aim of revolutionising techniques for railway track design, construction and maintenance.
Waste and resource management
My research in waste and resource management focuses on landfill science and engineering, and has led to the development of methods to improve resource recovery and reduce the pollution potential from landfills. I have worked on the design and engineering risk assessment of the low level radioactive waste repositories at Drigg, and from 2004-2010 I chaired the Technologies Advisory Committee for Defra’s £30M programme of research and demonstrator projects for new technologies for the treatment of biodegradable waste.
Affiliate research group(s)
How to access the heat beneath our feet by using building foundations to harvest thermal energy.
The disposal of Cement Kiln Dust (CKD) to landfill produces leachates with extreme properties of high pH and ionic species concentrations. The research has investigated a number of issues including: the properties of CKD, methods for the extraction of CKD rich leachate from landfills, the interaction of CKD with municipal solid waste and the anaerobic treatment of leachates with a high sulphate concentration.
This Knowledge Transfer (KT) project focused on the following key areas:
Bioenergy (especially methane production through anaerobic digestion, but also with potential for involvement in other areas e.g. other biofuels, production of pellets for local heat and co-firing in power stations, and pyrolysis of residual municipal wastes for syngas production)
Energy footprinting for process optimisation, both in industry and in the waste management sector
Energy efficiency studies within companies
Urban Sustainability studies (including participation in the Thameside Gateway Institute for Sustainability)
