Research Interests

Jasper’s research combines spectroscopy and molecular simulation to understand the electrode–electrolyte interface in lithium-ion batteries. His work focuses on aqueous electrolytes, which are non-flammable and cheaper to manufacture but limited by a narrow electrochemical stability window. He uses in-situ and ex-situ techniques (NMR, Raman, IR, XAS and XPS) alongside classical molecular dynamics, electrical double layer simulations and continuum theory to link electrolyte formulation to the chemistry that develops at the electrode surface. He is particularly interested in the role of diluents: their effect on solvation structure and the contribution of their sacrificial breakdown to interphase formation.

Biography

Jasper joined the Weatherup group in October 2021 to investigate the electrode–electrolyte interface in lithium-ion batteries and completed his DPhil in the Department of Materials at St Edmund Hall, University of Oxford. He is now a postdoctoral researcher in the group. He spent six months as a Drayton Research Fellow in the Bazant Group at MIT’s Department of Chemical Engineering, working on molecular simulation of concentrated aqueous electrolytes, supported by awards from the Drayton Fellowship, SCI, IOM3 and St Edmund Hall. Jasper received First Class honours in his bachelor’s degree in chemistry from the University of Warwick (2018–2021), where his research investigated bacterial strains capable of converting brown coal into green fuel.

His sporting interests include rugby, football, and swimming. Jasper represented the Oxford University Blues in 2024/25 and served on the St Edmund Hall RFC committee throughout his DPhil.
