About Me

My research interests broadly span computer graphics, particularly rendering, geometry processing, and scene representations. I am also interested in exploring compelling graphics problems beyond these areas.

I am a final-year undergraduate at the Hong Kong University of Science and Technology (HKUST), pursuing a BSc in Computer Science with an additional major in Mathematics. I conduct graphics research under Prof. Pedro V. Sander, currently focusing on spatial tiling with 4D Gaussian Splatting. I plan to pursue a PhD in computer graphics beginning in Fall 2027.
