    I am an Associate Professor at WMG, University of Warwick (UK) working in the area of sustainable materials and manufacturing. My main research interests are geared towards the use of waste, recycled and bio-based materials into commercial products and processes and understanding the overall environmental impact of those actions.

    Most recently, I have been leading research into the generation of hydrogen from wastewater treatment using microbial electrolysis cells. The focus of this work has been the application of recycled carbon fibre as electrode material in order to save cost and maintain performance. On a related project, investigations have been taking place on how to recover ammonia from the wastewater treatment system through the thermal decomposition of struvite.

    I have also been leading research on recycled carbon fibres in more traditional composite areas. Studies have been conducted on the application of recycled carbon fibres in thermoplastic and thermoset resins, aiming to understand the structure-processing-property relationships of these materials. Alternative composite materials have also been investigated, including the use of waste cooking oil as a feedstock for the synthesis of bio-based epoxy resins and their use within energy absorption structures. These resins have been successfully combined with carbon, glass and flax fibres.

    I also have an interest in understanding the environmental impact of our actions and how that might affect our decision making in the future. I have led research into developing sustainability assessments through the use of multi-criteria decision analysis as well as developing full life cycle models for the lithium-ion battery industry.

    I currently lead three undergraduate modules at the University: WM115 Engineering Materials, ES3E4 Life Cycle Engineering for Manufacturing Systems and ES4A8 Design for Sustainability
