1998-2001 Polymer Group, University of Cambridge.
Postdoctoral project entitled "Packing of fibre and filler particles in polymer composites" (supervised by Profs. Alan Windle and Anthony Kelly).

This project was a study of the physics of aggregation in polymer composites, such as polymer concrete, using both molecular dynamics and novel experimental techniques including X-ray microtomography. The aim was to optimise the mechanical properties and cost-effectiveness of the finished product, whilst maintaining the flow properties of the uncured mixture. This requires a detailed understanding of the geometrical rules which govern the packing of polydisperse distributions of complex shapes in three dimensions.

1995-98 Polymer Physics Group, University of Bristol.
PhD entitled "X-ray diffraction and computer modelling of perfluorinated ionomer membranes" (supervised by Dr. Simon Hanna).

The objective of the project, sponsored by National Power plc., was to optimise the performance of perfluorosulphonate ionomers in liquid electrolyte fuel cells. The morphology of these materials was examined using a combination of X-ray diffraction and molecular dynamics.

The X-ray data were analysed using the image processing language PV-WAVE, and related to the results of molecular modelling using novel methods such as maximum entropy and genetic algorithms. The modelling work itself was the first ever attempt to simulate the structure of ionomers in anything other than a phenomenological way.

The results of this work, which showed that ionomers form a selectively conductive ion-clustered morphology, were presented at the 18th Biennial meeting of the Institute of Physics as well as a number of national meetings organised by National Power. They have also been published in a number of peer-reviewed journals.
