Born in Birmingham, UK in 1954. Received a BSc degree with first class honours in chemistry from the University of Warwick in 1983. PhD was awarded in 1987 from the University of Southampton for the study of the shapes of small gas-phase molecules using laser-induced fluorescence and matrix isolation techniques. Carried out research for the Central Electricity Generating Board at Berkeley Nuclear Laboratories on the radiation chemistry of graphite moderators in UK Magnox and Advanced Gas-cooled Reactors (AGRs) until 1990, before joining CSIRO. Developed expertise in photochemistry, carrying out research into the processes that occur when materials are exposed to light and developing processes that use radiation to modify the surface properties of fibres. Invented the Siroflash process, involving continuous brief exposure of materials to UV radiation for preparing wool fabrics for printing, improving dye uptake and for preventing the pilling of wool and cotton knitwear. In 1996 won the US Innovative Technology Award from Radtech North America for his paper on SiroFlash and its importance in developing new applications for UV curing technology in textiles. Worked on new treatments to improve the brightness and photostability of wool and silk, which is a serious commercial problem when compared to cotton and synthetics, and on improving knowledge of the factors governing the photostability of dyed textiles. Work on the mechanism of wool photoyellowing resulted in the award (in March 2003) of the Gold Research Medal by the Worshipful Company of Dyers in London. Knowledge of the photochemistry and photostability of dyes has recently been applied to the new field of dye-sensitised solar cells (DSSCs), and a full patent has been applied for regarding the application of certain commercial textile dyes in Gratzel cells. Since 1994 he has secured over $6M of external funding for CSIRO, and was promoted to SPRS in 2004. Recently developed an interest in chemiluminescence techniques to study free radical oxidation reactions in polymers and also in proteins. Was awarded the Centenary Medal in 2008 by the Society of Dyers and Colourists (UK) for review papers on the photoyellowing of wool.
