Currently I supervise and conduct research into sustainable flame resistant materials, firefighting products and gas sensing nanotechnology.  The flame resistant materials include flexible polyurethane foam for comfort applications, coatings and membranes to protect flammable building cladding and timber, and treatments for textiles.  Firefighting products are primarily used to protect structures from bushfires, either through direct application of the product to the structure or to the surrounding vegetation.  The gas sensors have broad application to detect emission from fire, toxic materials or explosives.

As a Senior Research Scientist at BASF, I conducted basic research and product development in polyurethanes, including flexible foam, elastomers, fertilizer coatings and thermoplastic polyurethane (TPU).
