Dr Polly Burey
Dr Polly Burey is a chemical and materials engineer with expertise in developing fundamental understanding of the relationships between formulation, microstructure, processing and rheological behaviours of food materials developed over a 17 year industry-focused research career working with well-known food companies. Foods are intrinsically composite materials, and have some unique challenges in their analysis due to typically being soft-solid systems. Polly's past research in analysing food systems typically informs new product and process development. Dr Burey joined the University of Southern Queensland in 2017 where she heads up the Food Waste Valorisation Research Program Team and the new BSc Food Science major. Her current interests lie in development of useful products and energy offsets from food excess an processing by-products, specifically ingredients, nutritional products and composite materials, including bioplastics.
Materials engineering utilises mathematical analysis to define and quantify the physical response of materials to the application of a force. This has implications for determining whether a bridge will stand the test of time, which is purposely engineered to withstand force, to how easily chewable marshmallows are, which are deliberately engineered to be destroyed. In the exercise we will mathematically analyse shape change and strength properties of marshmallows. This will involve image analysis and mathematical analysis, as well as some eating of marshmallows.
I am a trained teacher and mathematics lecturer for the Tertiary Preparation Program at USQ with almost 10 years experience teaching in the tertiary sector. I am in the final stages of my PhD in computational topology, which I have been studying part-time at The University of Queensland, having presented my research both internationally and domestically.
During this talk I will provide an introduction to mathematics that uses our intuition from 2-dimensional and 3-dimensional space to describe objects in higher dimensions. I will focus on techniques and examples that let us visualise higher dimensional analogues of familiar objects such as cubes, spheres and tori. The talk will draw from current research but will be accessible and written for a non-specialist audience.
