BACKGROUND:

2005-Present: Chemical and Environmental Modeller, National Nuclear Laboratory.
2001-2004: Research Fellow, Centre for Radiochemistry Research, University of Manchester.
1996-2000 Department of Chemistry and Department of Earth Science, University of Manchester. Ph. D. Computational and Theoretical Chemistry.
1993-1996 Department of Chemistry, University of Manchester. BSc(Hons) Chemistry.

INTERESTS:
My main research interests are focussed on understanding the redox behaviour of Actinides under reprocessing conditions, long term storage and in the environment through the application of chemical modelling techniques, primarily quantum mechanics.
