About me

[CV]

I am a PhD candidate at Department of Computer Science and Engineering, UC San Diego. My advisor is Prof. Ravi Ramamoorthi. Before coming to UCSD, I obtained Bachelor of Engineering in Computer Science with First Class Honors from The University of Hong Kong. I was also once a research assistant at Department of Computer Science HKU advised by Prof. Yizhou Yu.

My research interests include various topics in computer graphics and computer vision, especially for appearance acquisition and 3D reconstruction.
