Dr Pre De Silva is a senior lecturer in Chemistry at the North Sydney campus of the Australian Catholic University. She obtained her PhD from the University of Aberdeen (UK). Before joining ACU she worked as a Lecturer at the University of Ruhuna (Sri Lanka), as a Postdoctoral Research Associate at the University of Lancaster (UK) and then as a Research Scientist in the Manufacturing and Materials Division at CSIRO.
Dr De Silva has extensive research experience in wider areas of chemistry. This includes the development of Eco-Friendly, Low-carbon binders (inorganic polymers) using industrial wastes, development of biomaterials in medical and dental applications, Waste waster purification technologies, CO2 mineral sequestration, Oil spill clean-up technologies and radioactive waste immobilization. She has served as a consultant for a number of industry based projects in the above areas.
