Ion Cyclotron Emission (ICE) is a strongly suprathermal emission brought on by instabilities within a fusion plasma. In its linear instability phase, the excitation mechanism for ICE is the magnetoacoustic cyclotron instability (MCI). As ICE is a passive diagnostic tool for fast ion physics, it is highly advantageous to apply knowledge gained from observing ICE to magnetically confined fusion (MCF) plasmas with the aim to improve tokamak efficiency and maintain the thermonuclear burn.
This project utilises HPC simulations to describe a minority energetic population of energetic (3.5MeV) alpha particles, and obtain spectra typical of ICE observations. Further work will look at simulating aneutronic fusion reactions to mitigate the ionisation of the tokamak inner wall, hence increasing the efficiency of tokamaks and their longevity.

Oct 2022 - Wrote a reflective piece on the development of my teaching style, as viewed through Brookfield's four lenses, for the Journal of PGR Pedagogic Practice (JPPP).
Masters
Obtained my MPhys (Physics w/ Astrophysics) in 2021 from the University of Exeter. My Supervisors were Prof. Sean Matt and Dr. Lewis Ireland. We worked on implementing a differential rotational profile at the star's surface using stellar wind model PLUTO, and measured its effect as a mechanism for torque down on a star.
