Zian Wang

I'm a PhD student at University of Toronto, affiliated at Vector Institute. My advisor is Sanja Fidler. I'm also a research scientist at NVIDIA.

I did my bachelor at Tsinghua University, advised by Yebin Liu. I started my adventure in research at Intelligent Vision Group, advised by Jiwen Lu and Jie Zhou.
