Cath Lister

I’m a PhD student on the community Fusion CDT programme based at the University of Aberdeen. My background is in chemistry and physics, most recently completing an MPhys at the Open University where I became interested in theoretical plasma physics. My fascination with fusion began with stellar nucleosynthesis, which led me to transition to terrestrial fusion as a way of applying the theoretical physics I enjoy to a problem that could meaningfully contribute to the global energy transition.

My project investigates how plasmas interact with tungsten surfaces in the divertor region of tokamaks, where managing heat exhaust is a known challenge. The plasmas at the tokamak edge form complex systems in which low-temperature plasma chemistry overlaps with the high-temperature physics of fusion reactors. My research aims to connect surface interaction models with fusion edge plasma models to better understand how processes such as plasma recombination, sputtering, and impurity transport influence detachment behaviour in the divertor. The project also involves collaboration with Hephaestus Technologies, a private company developing AI systems for fusion plasma modelling, providing opportunities to use fundamental plasma physics in industrial applications.
