Tunable X-ray imaging
Using photon energy as another degree of freedom in imaging. I investigate how the source spectrum, materials and detector response affect contrast.

PhD candidate
School of Electrical and Electronic Engineering
Nanyang Technological University, Singapore
I’m pursuing a PhD at NTU under the Nanyang President’s Graduate Scholarship (NPGS), with a research focus on quantum science. My work explores X-ray photonics, free electrons and light–matter interactions.
I have founded two start-ups and bring over a decade of 3D-printing experience to prototyping, workshops and training. Through Fix It Today, I work to make 3D printing more accessible to hobbyists, students and professionals.
What I work on
Research
Quantum nanophotonics
Exploring how nanostructures and light–matter interactions shape the generation and behaviour of X-rays and free-electron radiation.
2D-material photonics
Studying how strain and laser annealing change light emission in atomically thin materials, including emission wavelength and carrier lifetime.
