Catherine Whitby completed a BSc (Hons) at the University of New South Wales and a PhD in Chemistry at the University of Melbourne. She was an ARC Future Fellow at the University of South Australia, before moving across the ditch. She is now Associate Professor of Chemistry at Massey University. Catherine is interested in surface chemistry and its role in food structure and function. Her current focus is on using proteins to modify the surfaces in emulsions so they can reconfigure (re-organise their structure). Designing self-healing interfaces will benefit the stability of emulsions subjected to large deformations during processing, or their final application.
