My research is centred on understanding and optimising the interactions between particles and liquids in industrial and environmental systems to improve process efficiency, resource recovery, and sustainability. During my PhD, I investigated the behaviour of insoluble molten lignin globules in aqueous environments during the pre-treatment of woody biomass, developing fundamental knowledge of particle–liquid interactions in bioresource processing. Building on this foundation, my research has examined the surface properties of mineral particles and their interactions with flocculants, reagents, and emulsions to enhance mineral recovery while reducing energy and water consumption. This work aligns with my broader goal of advancing circular economy principles within resource processing industries.

More recently, I have expanded my research into additive manufacturing and sustainable materials. My work includes a published review on the role of powder properties and bulk flow behaviour in additive manufacturing processes, as well as research exploring the use of 3D-printed photoelastic particles to improve understanding of complex particle geometries and behaviour. I am also investigating pathways for converting plastic waste into 3D-printing filament, supporting the development of circular manufacturing approaches that reduce waste and the environmental footprint of production. My interest in additive manufacturing has also extended beyond technical performance to the broader societal implications of emerging technologies. During the COVID-19 pandemic, I developed a 3D-printed wearable device designed to monitor elevated body temperature. This work prompted a broader exploration of the ethical considerations associated with integrating 3D-printed products into society, culminating in a multidisciplinary book chapter examining the responsible adoption of additive manufacturing technologies.

My current research focuses on the application of Life Cycle Assessment (LCA) and digital technologies to evaluate and improve the sustainability of engineering processes. This includes investigating the environmental impacts of additive manufacturing systems and integrating Artificial Intelligence techniques to predict and categorise environmental impacts associated with materials and manufacturing choices. Through this work, I seek to support evidence-based decision-making and the development of more sustainable engineering practices.

Looking ahead, I aim to further strengthen my research program in circular economy and resource recovery by returning to an area that first inspired my research career: the valorisation of food waste into valuable products. By combining expertise in particle science, resource recovery, life cycle assessment, and sustainable manufacturing, I seek to develop innovative solutions that transform waste streams into valuable resources and contribute to a more circular, resilient, and sustainable future.

Alongside my research activities, I supervise Final Year Project (FYP) capstone students, master's research projects, and PhD candidates, supporting the development of future engineers and researchers while fostering a collaborative and research-driven learning environment.
