Overview
Background
Dr. Pratheep Annamalai is a polymer and nanomaterials scientist with a keen interest in engineering materials for sustainable living. He is an Adjunct Senior Research Fellow at the School of Agriculture and Food Sciences. He has extensive expertise in both translational and fundamental research using nanotechnological tools towards sustainability. Currently, he is interested in alternative proteins and valorisation of agricultural crops and food waste into reactive, building blocks for improving the performance and utility of bioproducts. Thematically, his research focuses on
- Food Processing (plant-based food products)
- Bioproducts (from agri-food waste)
- Sustainable building blocks (for advanced materials).
Before joining UQ, Pratheep studied Chemistry in University of Madras, received PhD in Chemistry from University of Pune (India), then went on to work as a postdoctoral researcher on hydrophobic membranes at the Université Montpellier II (France), and on ‘stimuli-responsive smart materials’ at the Adolphe Merkle Institute - Université de Fribourg (Switzerland).
Upon being instrumental in the discovery of ‘spinifex nanofibre nanotechnology’ and establishing Australia’s first nanocellulose pilot-plant, he has been awarded UQ Excellence awards for leadership and industry partnerships for 2019. Recognising his contribution to the nanomaterials, polymer nanocomposites, polymer degradation and stabilisation regionally and globally, he has been invited to serve as a committee member for ISO/TC229-WG2 for characterisation of nanomaterials (2016), a mentor in TAPPI mentoring program (2018), guest/academic editor for various journals (Fibres, Int. J Polymer Science, PLOS One). He has served as a member of the UQ-LNR ethics committee for reviewing the applications (2017-) and a member of the AIBN-ECR committee in 2014.

Research impacts
Spinifex nanofibre nanotechnology The spinifex nanofibre nanotechnology has led to: 1) the benefit-sharing landmark agreement between Indigenous Australian community and UQ in 2015 ensuring the ongoing equity and involvement of their indigenous community in the project, 2) establishment of first nanocellulose pilot-scale plant in UQ Long Pocket Precinct with a 5kg/day production capacity by the support of both state and federal governments, and 3) promotion of the systematic harvesting of spinifex grass in regional Australia potentially providing training, jobs, and education in regional Australia, aligning with the major effort 'Closing the gap' by government. Over last seven years, this partnership has single-mindedly supported further R&D for utilising it as renewable functional additive for improving strength and durability of a wide range of materials spanning from rubber, recycled papers to building materials like cement and concrete.
