I am working towards a DPhil (PhD) under the supervision of Felix Parra (University of Oxford) and Jon Hillesheim (CCFE). My work is focused on understanding the interaction between microwaves and plasma turbulence to analyse data from the Doppler Backscattering (DBS) diagnostic. Specifically, I am using beam tracing and the reciprocity theorem to elucidate said diagnostic in general geometry. DBS is especially important for future tokamaks as it is one of the few available diagnostics which are robust enough to withstand high neutron fluxes. We hope to subsequently apply our analysis to other diagnostics, such as cross-polarisation scattering and high-k scattering.
Before embarking on graduate studies, I worked on photonics and plasmonics at the Agency of Science, Technology, and Research (A*STAR) in Singapore for a year, where I co-authored several papers and a book chapter. My undergraduate degree was in Natural Sciences (University of Cambridge), while my pre-university education was in Singapore. Both my undergraduate and graduate studies are sponsored by a scholarship from A*STAR. My hobbies include photography and cooking, and I am always on the lookout for new dishes to characterise and add to my repertoire.
