Current research and/or projects

Biography:

I have a deep passion for discovery and building new knowledge. The freedom in youth nurtured my scientific enquiry. Over 35 year career in inter-disciplinary scientific research and leadership still assert an undiminished joy in: unravelling stability mechanisms for films, suspended coals, clays, emulsions, bitumen/oil, tailings with polymers and surfactants; I develop new concepts, lead and direct innovative research, built state of art laboratory for interfacial phenomena in multiphase systems, fluid flow.
