About Me (CV)

I am currently a post-doctoral researcher with Prof. Luc Van Gool in the Computer Vision Laboratory (CVL) at ETH Zurich.

Before coming to Zurich, I obtained my PhD degree from The Chinese University of Hong Kong in 2015. During my PhD study, I was with the Multimedia Lab under the supervision of Prof. Xiaoou Tang, and I worked closely with Prof. Yu Qiao. I received B.S. degree from Nanjing University, supervised by Prof. Tong Lu, in 2011.
