Profile Summary

I'm a PhD Candidate in Biostatistics and Machine Learning at The University of Hong Kong. I received my MSc from Imperial College of London with Distinction where I also received the Winton Capital Prize for the best research project among my peers. My MSc thesis on Non-Compliance in Randomised Controlled Trials is publicly available on arXiv: https://www.arxiv.org/abs/2503.17692. The first paper of my PhD which proposes a supervised extension on Principal Component Analysis is also publicly available on arXiv: https://arxiv.org/abs/2506.19247. I'm currently working on incorporating dimensionality reduction techniques in observational studies for reducing confounding.
