I’m a PhD researcher in quantum sensing at the Adelaide University, focused on developing diamond-doped optical fibres for magnetic-field sensing. My work sits at the intersection of fibre fabrication, laser physics, NV-centre photonics, and materials science. I design and fabricate custom fibres (cane-in-tube, stacked canes, interface-doped structures), optimise drawing conditions, test NV fluorescence under 532 nm excitation, and evaluate the trade-offs between fluorescence performance, scattering losses, and fibre geometry. I'm also building expertise in fusion-splicing diamond-doped canes and characterising optical behaviour for real-world sensing applications. Outside the lab, I communicate science through competitions (Runner-Up, 3MT 2025 and Third Place, VYT 2025), outreach, and mentoring first-year PhD candidates. I’ve also been featured by Study Australia for representing international researchers in Adelaide. My long-term goal is to work across photonics R&D, fibre-optic systems, quantum sensors, and advanced material technologies, wherever hands-on experimental capabilities and the ability to turn complex ideas into working prototypes are required.
