Dr Matthew Royle was a Research Assistant for the UKRI Interdisciplinary Centre for Circular Chemical Economy at Newcastle University. He worked with the Centre and Professor Libby Gibson to unify efforts across the three work themes by preparing a roadmap showing the current status and future prospects for the Circular Economy of Olefins. Matt has a background in physical chemistry, studying a PhD at Durham University. His PhD focused on the phase behaviour of limonene microemulsions and how they interact with oil, with an emphasis on the kinetic processes of micelle exchange. Matt has now joined DEFRA as one of their R&D fellows working on plastic and textile material flows for the data observatory.
