Topic: Kinetic simulations of Ion Cyclotron Emission (ICE) in plasmas

Funding: EPSRC

Background: Theoretical Physics (MPhys), University of York, 2015

Project outline:

My research focuses on the collective radiative instability Ion Cyclotron Emission (ICE). The excitation
mechanism for ICE is the magnetoacoustic cyclotron instability, which is a potential diagnostic for
alpha particle confinement in ITER. Using large scale high performance computing facilities, I employ
numerical simulations of the nonlinear kinetic physics associated with ICE using the Warwick developed
particle-in-cell (PIC) code EPOCH in collaboration with researchers from the UK, Japan, and Korea.

My GitHub page includes tutorials for various programming languages. So far there are tutorials for: Fortran, C++, BASH, Python, MPI, OpenMP. There's also other miscellaneous sutff.
