Biography
I have been a lecturer in the Department of Chemistry since 2023 and a UKRI Future Leaders Fellow since 2024.
My research involves the discovery and development of new materials for energy applications, such as batteries and fuel cells. My group uses a combination of computational and experimental materials chemistry techniques to understand the complex relationships between the structure of materials and their performance in sustainable energy devices.
Public engagement
Discussion of battery sustainability on the Zwittering On podcast.

Research Overview
My group focuses on developing combined experimental and computational tools for the discovery and characterisation of sustainable next-generation materials for energy applications, including rechargeable batteries and fuel cells. My group uses computational methods to understand the long timescale atomistic dynamics in the bulk and at the interfaces of energy materials, using techniques such as transition state searching and Monte Carlo methods. I also work on the development of novel cathode and solid-state electrolyte chemistries for Li and beyond Li-ion batteries with improved sustainability from materials synthesis to end of life.
