Catherine is a Senior Lecturer in Chemistry, appointed in late October 2014. Prior to this she was an ARC Future Fellow and Senior Research Fellow at the Ian Wark Research Institute at the University of South Australia. She is a physical chemist with expertise in colloid and surface chemistry. She uses nanomaterials to modify the chemistry of drop and bubble surfaces. This strategy enables her to control the structure, stability and flow of soft materials. Her findings have been applied in food and pharmaceutical products and in drilling fluids.
I am interested in the edges (surfaces and interfaces) that control the properties of materials like paints, sunscreens, lubricants and dairy foods. All these materials are colloids. They are made of drops, bubbles and particles dispersed in a liquid. The drops, bubbles and particles are nanometres to micrometres in size.
I investigate how the chemical properties of drop (bubble or particle) surfaces control how colloidal materials flow and behave. A focus of my work is on using nanomaterials to modify the drop and bubble surface chemistry. This strategy enables me to tune the structure, stability and flow of soft materials used in food, pharmaceutical and agricultural products.
I use microscopy and rheology tools to do my research. I use these techniques to probe inside colloidal materials and investigate their physical and chemical properties.
