Overview
Background
Professor Jason Stokes is a Professor in the School of Chemical Engineering at The University of Queensland and Program Lead for Premium Food and Beverages within Australia’s Food and Beverage Accelerator (FaBA), providing leadership across a nationally coordinated, industry‑focused research program. His work sits at the interface of chemical engineering, soft matter science and food systems, combining fundamental research with strong industry engagement.
Jason is internationally recognised for his expertise in rheology, tribology and interfacial phenomena, with particular emphasis on how structure, flow and deformation govern the behaviour of complex fluids and soft materials. He is known for pioneering experimental approaches in soft‑contact tribology and aqueous lubrication, providing new physical insight into oral processing, mouthfeel, texture and material performance across multiple length scales.
With more than 25 years’ experience working in and with industry, Jason has led long‑term research partnerships spanning food and beverage manufacturing, materials processing and sustainability‑driven innovation. Prior to joining UQ in 2008, he worked as a Research Scientist at Unilever R&D in the United Kingdom. His current research supports the rational design of next‑generation food and beverage products, including plant‑based and value‑added formulations, by integrating processing, structure and performance.
Jason was named among Australia’s Top 250 Researchers by Research Magazine (The Australian, 2026), ranking first nationally in Dispersion Chemistry within Chemical and Materials Sciences. He has an h‑index of 60 (Google Scholar), reflecting sustained international impact across rheology, tribology and food engineering.
Teaching and research training
Jason’s teaching and supervision are strongly research‑led and industry‑engaged, with a focus on developing deep physical intuition, independent thinking and problem‑solving capability in chemical engineering graduates. He has extensive experience in HDR supervision and research training, mentoring PhD, Masters, Honours students and postdoctoral researchers across interdisciplinary projects in food engineering, soft matter and materials processing.
His teaching is grounded in fluid mechanics and transport phenomena, with long‑standing involvement in undergraduate fluid‑flow and particle‑based courses, as well as undergraduate research‑thesis coordination and supervision. He is widely recognised by students for clear, structured explanations of complex concepts, an enthusiastic and approachable teaching style, and for integrating real‑world engineering context into learning. He places strong emphasis on scientific rigour, career development and an inclusive, supportive research culture, and has contributed to researcher development and wellbeing through leadership roles within the School and Faculty.
Jason currently coordinates and teaches Transport Phenomena (CHEE4009) and Engineering Placement (ENGG7292).

Premium Food and Beverages Innovation (FaBA / PreFaB)
This research supports industry‑led innovation in premium food and beverage products through the Food and Beverage Accelerator (FaBA). It focuses on understanding how structure, properties and processing determine product quality, functionality and consumer acceptance. Projects bring together industry and academic expertise to address challenges in sustainable, ethical and value‑added food production in Australia.
-
Food Oral Processing, Texture and Sensory Performance
This research examines how food structure and material properties govern oral processing, texture, lubrication and sensory perception. Using rheology, tribology and interfacial science, it links in‑mouth behaviour to formulation and processing of liquids, semi‑solid foods and solids. Outcomes support the rational design of foods with improved sensory performance, nutrition and consumer acceptance.
-
Rheology of Soft Materials and Complex Fluids
This research focuses on the rheology of soft materials and complex fluids, including non‑Newtonian and multiphase systems. It adopts a multiscale transport‑phenomena perspective, examining how behaviour across different length and time scales—from microstructure and interparticle interactions to macroscopic flow and transport pocesses—governs material response and process performance. Applications span food, bio‑based materials, personal care, biomedical systems and industrial suspensions.
-
Aqueous Lubrication and Soft‑Contact Tribology
This research investigates friction, lubrication and wear in soft‑contact systems where compliant surfaces interact through aqueous and complex fluids. It explores how fluid rheology, surface interactions and deformation govern lubrication behaviour in biological, food and engineered systems. The work advances understanding of soft‑contact tribology beyond traditional hard‑surface models.
-
Food Processing, Engineering and Extrusion
This research applies chemical engineering principles to food processing, separation and extrusion technologies. It integrates transport phenomena, rheology and materials characterisation to understand how processing conditions influence structure and functionality. The work supports development of scalable processing strategies for plant‑based and value‑added food products.
-
Anisotropic Soft Materials, Colloids and Nanocellulose Systems
This research investigates anisotropic soft materials formed from colloidal rods and interacting colloidal systems, including nanocellulose and fermentation‑derived celluloses. It examines how particle shape, surface interactions, self‑assembly and liquid‑crystalline ordering control rheology, gelation and mechanical properties. The work advances understanding of how colloidal interactions give rise to solid‑like behaviour and supports the design of bio‑based materials with tunable structure and functionality.
Research impacts
Jason’s research has delivered measurable impact across the food, materials and manufacturing sectors by enabling industry to design products and processes based on physical understanding rather than trial‑and‑error experimentation.
His work on rheology, tribology and soft‑matter behaviour has been applied directly by industry partners to improve the texture, mouthfeel, stability and processing performance of food and beverage products. These outcomes have supported the development of healthier and more sustainable foods, including texture‑modified products for vulnerable consumers and plant‑based formulations with improved consumer acceptance.
These industry partnerships are characterised by a strong emphasis on research‑led translation, linking fundamental and strategic research with applied R&D and implementation in industrial settings. Through long‑term strategic partnerships with Australian and global food and beverage companies, Jason’s research has:
- translated fundamental and strategic research into applied R&D and manufacturing‑relevant outcomes, supporting continuous innovation over extended timeframes
- reduced development time, formulation uncertainty and material waste by replacing trial‑and‑error approaches with research‑driven, physics‑based design principles
- improved process efficiency, robustness and product consistency, enabling more reliable translation and scale‑up in industrial environments
- supported onshore value‑adding by embedding advanced materials, rheology and processing expertise within Australian food manufacturing contexts
- built workforce capability through long‑running, industry‑embedded HDR and postdoctoral projects that connect research training directly with industrial practice
As Program Lead for Premium Food and Beverages within Australia’s Food and Beverage Accelerator (FaBA), Jason’s work supports national priorities in food innovation, sustainability and advanced manufacturing, delivering benefits that extend to economic growth, health and wellbeing, and environmental outcomes.
