We are the Complex Fluids Group at UNSW. Our team works with industry and academic partners to design smart fluids with unique response and flow behaviour linked directly to product and material performance.

Fluids containing small amounts of colloids, polymers, and surfactants can exhibit highly non-ideal behaviour with fascinating dynamics. Complex fluids are a key part of most major products and manufacturing processes. Our group uses advanced imaging and rheology techniques to understand fundamental properties of complex fluid components, specifically: shape, structure, and flow.

Research Interests: Design and development of microstructured fluid materials by understanding their kinetic behavior. Most of our work deals with complex fluids, fluids containing small amounts of colloids, polymers, and surfactants that exhibit highly non-ideal behaviour with fascinating dynamics. Complex fluids are a key part of most major products and manufacturing processes. Our group uses advanced imaging and rheology techniques to understand fundamental complex fluid properties.

Here you can find the current group members, as well as an archive of the completed works of past members. We have a core team of researchers and usually have several overseas visitors and short-term project students around! The group is committed to diverse membership and perspectives to ensure continued innovation.
