Dr Samira Siyamak

Senior Research Fellow

Samira applies her expertise in biopolymer chemistry and reactive extrusion to develop sustainable and functional food products by exploring the links between formulation, processing, and material properties.

Samira holds a PhD in Chemical Engineering (UQ). Her research is focused on applying extrusion technology to develop innovative and functional food products. With a strong background in biopolymer chemistry and specialised expertise in reactive extrusion, she investigates the relations between formulation, processing conditions, microstructure, and the physico-chemical properties of food macromolecules and biopolymers. Her work aims to advance the development of sustainable solutions for the food industry.
