I am a Research Assistant for the UKRI Interdisciplinary Centre for Circular Chemical Economy at Newcastle University. I am working 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. I have a background in physical chemistry, studying a PhD at Durham University. My 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. [Read more]

My interests lie in the use of modelling and optimisation at different scales e.g. technologies, processes and value chains with a view to quantifying performance at a range of scales and supporting decision-making. I’ll be supporting Benoit Chachuat in Theme 2. [Read more]

Preetam is a Research Associate in the Department of Chemical Engineering with Professor E. Yu. His research activities involve the development of nanocatalysts and electrochemical reactors for carbon dioxide utilisation.
