Introduction
I am a geochemist, specialising in low temperature interactions between groundwater, rock, cement and wastes, especially as they relate to environmental protection and resource efficiency. I have interests in mineral processing technologies (refining and synthesis in molten salts, ultrasonics and electrokinetic dewatering of solids) and in computational thermodynamics. Much of my work has focused on geological aspects of waste management, both the underground storage of nuclear waste and in near-surface barriers to control pollution migration. My private practice is described in more detail on the consultancy page, but includes:
- Thermodynamic simulation of near field processes
- Cement chemistry, especially as it applies to waste management
- Low-embodied energy construction materials
- Novel sorbents derived from waste materials
- Mineral processing technologies
- Resource-efficient materials and materials re-use

MIRO
I work as a Research Manager for MIRO, the Minerals Industry Research Organisation, where I manage projects and develop new ideas of benefit to MIRO's member companies. I have been associated with MIRO for over ten years, having served on the Research Advisory Panel (AIMRAP) and have worked as a contractor on several MIRO projects. Our current work is detailed on my MIRO page and more information is on the MIRO website
University Research
Around half of my work is in close association with the UK universities and more details can be found on the relevant pages. I joined Imperial College as a Research Fellow in 1997 after some years as Senior Geochemist with W.S. Atkins' consulting practice in Epsom. My work there continues with the Materials Department in the Royal School of Mines, but I am increasingly involved with the Department of Civil and Environmental Engineering. Most of my research at Imperial has been concerned with Cement Chemistry, both through theoretical (thermodynamic modelling) and experimental studies. I served as Research Manager for the (then) Miniwaste Faraday Partnership whilst at Imperial, which has since evolved into the UK Resource Efficiency Knowledge Transfer Network. I have been fortunate in having some excellent students, both as personal tutees and as supervised research students and am pleased to continue this role, despite not being at Imperial every day.
In recent years, I have worked closely with University College, London, where I am a Senior Research Fellow in the Department of Chemical Engineering. My work there is a collaboration on two projects concerned with molten salt chemistry; one on mineral refining and one on cement mineral synthesis. I have also collaborated for some while with the Industrial Minerals Group (originally at Birkbeck College) who now are part of the UCL Materials Chemistry Centre. Much of this work is synchrotron science and my collaborations have been on sulphate minerals and cement carbonation. Both studies have required long hours at the Daresbury synchrotron in Cheshire and will, in due course use the new DIAMOND light source near Oxford. The third department with whom I collaborate at UCL is Civil Engineering, where we are investigating routes to the safe management of electroplating wastes. My scientific contribution there is largely in using thermodynamic calculations to better understand the system chemistry.
