About Me

I am currently a research lead at TikTok. I was a research scientist at Facebook AI Research, and an early member of the Amazon Go team that built the computer vision system to replace human cashiers for retail. Before moving to US, I was a postdoc in the LEAR Team, INRIA with Cordelia Schmid. I received my Ph.D. in Computer Vision from Chinese Academy of Sciences, and B.S. in Electrical Engineering from Harbin Institute of Technology.

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. The best way to contact me is via my e-mail: .
