Hongyu LIU

PhD Candidate

I am a second-year Ph.D. student at the Department of Computer Science and Engineering, HKUST advised by Prof. Qifeng Chen.
Before joining HUKST. I spend two wonderful years in Huya as a computer vision engineer led by Xintong Han and Jia Xu. I was an intern at Tencent AI Lab advised by Yibing Song and Wei Liu. Meanwhile, I have cooperated many times with my good friend Ziyu Wan. My research interests include 2D/3D Generation, digital human, neural rendering and contrastive learning.
I am now in Ant Research as an intern supervised by XuanWang. And I will focus on 3D Generation.
I love fishing very much, and my dream is to go fishing all over China!
