Profile

I graduated from the University of Bristol in 2005. After a brief stint in industry, I pursued my PhD at the University of Sheffield, where I continued as a postdoctoral researcher until 2016. That year, I began my academic career as a University Academic Fellow at the University of Leeds, eventually being promoted to Associate Professor in 2021. In 2024, I returned to the University of Sheffield as a Chair in Sustainable Materials within the School of Chemical, Materials, and Biological Engineering.

My research team focuses on integrating polymerisation chemistries with innovative technologies such as flow chemistry, online monitoring, and artificial intelligence to drive advancements in polymer sciences. The overall vision is to enhance the sustainability of polymer products and processes. I actively collaborate with academic and industry partners to ensure versatility of the technologies and that my research has practical applications which can meet societal needs. These collaborations help bridge the gap between academic research and industrial implementation, fostering innovation and accelerating the development of sustainable materials. My interdisciplinary research contributions to date have resulted in being awarded the 2022 Macro Group UK Young Researchers Medal, and the 2023 RSC Reaction Chemistry & Engineering Outstanding Early Career Paper Award.
