When I was young, I tried to research and write papers about the optimal angle when shooting basketballs, which marked the start of my research journey. Afterwards, I have been actively seeking for research opportunities. I took H3 Science Research in National Junior College (NJC), where I got a chance to research in Agency for Science, Technology and Research (A*STAR) for 1 year. In National University of Singapore (NUS), I proactively chose modules with research aspect to enrich my research experience. I enrolled in the Undergraduate Research Opportunity Programme under the supervision of Prof. Bryan Kian Hsiang Low and the paper has been accepted into the AAAI-24 conference.

Currently, I am preparing for my Integrated Honours Project (IHT) thesis.
