About Me

I am a final year master's student in computer vision at Carnegie Mellon university. Previously, I obtained Bachelor of Science in Mathematics and Information Engineering with first-class honors from the Chinese University of Hong Kong, where I had the pleasure to work on computer graphics with Professor Chi-Wing Fu. I was also honored to work as a research intern at SenseTime with Professor Jifeng Dai and Hao Li.

Currently, I am working on my capstone project at R-PAD lab led by Professor David Held on 3D scene understanding.
