Biography

I'm currently a full-time Applied Scientist at AWS AI Labs, working with Tianjun Xiao, Tong He, Dr. Zheng Zhang, Dr. Francesco Locatello, and Prof. Thomas Brox. Before joining Amazon, I received my M.S degree in Computer Science from Chinese Academy of Sciences, advised by Prof. Hui Chen, and B.S degree in Computer Science from University of Science and Technology Beijing, under the supervision of Prof. Xu-Cheng Yin and Prof. Weiming Dong. I was a research intern at Bytedance AI-Lab and Baidu VIS, respectively. Also, I was fortunate to work with Prof. Nadia Magnenat Thalmann (Nanyang Technological University), Prof. Noa Garcia (Osaka University) and Prof. Yuta Nakashima (Osaka University).

My research interests include computer vision, deep learning, and virtual reality.
