About me

I am a PhD student at Department of Computer Science and Engineering, UC San Diego. And my advisor is Prof. Ravi Ramamoorthi. Before going 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 image processing, light field camera, and machine learning.
