I am a research scientist at Facebook AI since 2017. I was research scientist at Amazon Seattle, building computer vision systems for the "Just Walk Out" feature of Amazon Go. Before moving to US, I was a postdoc in the LEAR Team, INRIA with Cordelia Schmid. I received my PhD in Computer Vision from Chinese Academy of Sciences in 2012, and B.S. in Electrical Engineering from Harbin Institute of Technology in 2006.

My research interests range from low-level vision to high-level vision with a focus on video understanding. You can find more detailed information in my CV and my old homepage.
