Professional Biography

  • Senior Lecturer in Chemistry in the Institute of Fundamental Sciences at Massey University, from late October 2014 onwards
  • ARC Future Fellow and Senior Research Fellow, Ian Wark Research Institute, UniSA working on controlling Pickering emulsion destabilisation (March 2010 to September 2014)
  • Research Fellow, Ian Wark Research Institute, UniSA working with John Ralston on particle attachment to drops and bubbles (October 2006 to February 2010)
  • Gritton Postdoctoral Fellow, School of Chemistry, University of Sydney working with Greg Warr on using neutron scattering techniques to characterise emulsions (April 2005 to September 2006)
  • Postdoctoral Research Associate, Department of Chemistry, University of Hull, working with Bernie Binks on Pickering emulsion projects funded by Rhodia Services and Halliburton Energy Services (November 2001 to March 2005)

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.

Research Expertise

Research Interests

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.
