Heather attained her Bachelor of Technology degree in food engineering from Massey University. She then spent 10 years in gelatine manufacture in various roles including quality assurance, production management and process improvement engineering. In 2015 she completed her PhD study into the rheology of biopolymer soft particle suspensions, supervised by Professor Jason Stokes at the University of Queensland. She has since continued at UQ in postdoctoral roles investigating the relationship between rheological properties, food structure and sensory perception of real food products and model soft particle suspensions with a focus on dairy protein systems. The key outcomes from the project have allowed our industry partner to move towards the rational design of food products.

Jason Stokes is a Professor in the School of Chemical Engineering and leads the Premium Food and Beverages Program in Australia’s Food and Beverage Accelerator. This program focuses on industry-driven research to enhance onshore value-adding and business growth opportunities.

Jason is a recognized expert in the rheology, lubrication, structure and processing of complex fluids and soft material, including food and beverages. He pioneered the development of rheology and soft contact tribology techniques to provide new insights into oral processing and sensory perception that includes mouthfeel, taste and flavour.
