Viscoelastic Lubrication
The project aims to develop new principles of viscoelastic lubrication in soft contacts. New insights into friction behaviour arising from complex fluid-substrate interactions are expected to be generated using techniques and interdisciplinary approaches that bridge rheology, tribology and surface science. Outcomes from the research should provide significant benefits to diverse fields including advanced materials and complex fluids, engineering tribology, biolubrication and food structure design.
This project is associated with an Australian Research Council Discovery Project.

Plant-based foods and meat analogues
The project aims to address the need for engineering plant-based food products to deliver a sensory experience akin to meat. The project expects to generate new knowledge on the structural drivers for emulating meat-like texture and taste within burger products. Expected outcomes of this project include new ingredients and food characterisation methodologies, including rheology and sensory, which can be employed in rational food structure design. This should provide significant benefits in enhancing the consumer acceptance of plant-based foods that is required to support the rapidly growing market opportunity for them and sustainable food production. The specific focus here will be on developing a fundamental understanding of the different types of proteins, their confirmation, purity etc., and structural anisotropy obtained using different methodologies including processing, contribute to the overall mechanical response (linear and nonlinear) of mixed-biopolymer gels. It is anticipated the project will utilise a newly acquired lab and pilot-scale extruders to enable translation of fundamental knowledged into product-related outcomes.
This project is associated with industrial partnership with a plant-based foods start-up company out of Boston, USA.

Food Oral Processing and Food Structure Design
Projects seek to relate physical measurements such as rheology and tribology to the flow and deformation of foods during consumption that affects sensory perception and consumer preferences. We are particularly interested in connecting chemical engineering, physiology, and food sensory science. These studies are used to assist industry to rationally design processed foods and beverages with consideration for formulating consumer acceptable healthy & nutritious foods and sustainable process engineering. One area of interest is in designing food systems using plant based ingredients.
This project is associated with on-going partnerships with industry.

Viscoelastic Lubrication
The project aims to develop new principles of viscoelastic lubrication in soft contacts. New insights into friction behaviour arising from complex fluid-substrate interactions are expected to be generated using techniques and interdisciplinary approaches that bridge rheology, tribology and surface science. Outcomes from the research should provide significant benefits to diverse fields including advanced materials and complex fluids, engineering tribology, biolubrication and food structure design.
This project is associated with an Australian Research Council Discovery Project.

Plant-based foods and meat analogues
The project aims to address the need for engineering plant-based food products to deliver a sensory experience akin to meat. The project expects to generate new knowledge on the structural drivers for emulating meat-like texture and taste within burger products. Expected outcomes of this project include new ingredients and food characterisation methodologies, including rheology and sensory, which can be employed in rational food structure design. This should provide significant benefits in enhancing the consumer acceptance of plant-based foods that is required to support the rapidly growing market opportunity for them and sustainable food production. The specific focus here will be on developing a fundamental understanding of the different types of proteins, their confirmation, purity etc., and structural anisotropy obtained using different methodologies including processing, contribute to the overall mechanical response (linear and nonlinear) of mixed-biopolymer gels. It is anticipated the project will utilise a newly acquired lab and pilot-scale extruders to enable translation of fundamental knowledged into product-related outcomes.
This project is associated with industrial partnership with a plant-based foods start-up company out of Boston, USA.

Food Oral Processing and Food Structure Design
Projects seek to relate physical measurements such as rheology and tribology to the flow and deformation of foods during consumption that affects sensory perception and consumer preferences. We are particularly interested in connecting chemical engineering, physiology, and food sensory science. These studies are used to assist industry to rationally design processed foods and beverages with consideration for formulating consumer acceptable healthy & nutritious foods and sustainable process engineering. One area of interest is in designing food systems using plant based ingredients.
This project is associated with on-going partnerships with industry.

Programming anisotropy into responsive soft materials
Our recent discovery of using nanocrystalline cellulose colloidal rods to contstruct a Liquid crystal hydroglass (LCH) provides an exciting avenue to control the structural hierarchy and hence properties of soft materials. LCH is a biphasic soft material with flow programmable anisotropy that forms via phase separation in suspensions of charged colloidal rods upon increases in ionic strength. This project aims to expand on the materials space for LCH materials in order to create viscoelastic materials with complex rheology as well as structural, mechanical and optical heterogeneity. The intended outcome is enabling the creation of anisotropic materials with shape-memory and shape-restoring features for the realization of artificial muscles, novel biomedical devices, soft robotics and morphing structures. .
This project is associated with an ARC Discovery Project.
