About Me

I am a staff research scientist at Google, working closely with Cordelia Schmid and Kevin Murphy. I have received my Ph.D. from University of Southern California in 2015, advised by Prof. Ram Nevatia. During graduate school, I was lucky enough to work with Sanketh Shetty and Rahul Sukthankar at Google Research; Lubomir Bourdev, Ronan Collobert and Manohar Paluri at Facebook AI Research. Before coming to the U.S., I received my bachelor degree in Computer Science at Tsinghua University in 2011. And even before that, I attended Yaohua High School in Tianjin, China.

My research focus is on video understanding, with the goal to build machine intelligence that understands and anticipates human activities, and ultimately develop autonomous machines that interact with and assist us in unconstrained environments. My research has been recognized by two winning entries at COCO object detection challenge 2016 and iNaturalist challenge 2017, a best paper finalist at CVPR 2019 and media coverage from WIRED, TechCrunch, etc.

Here are a few representative recent publications:

Self-supervised and Cross-modal Learning
Behavior Prediction for Interacting Agents
Detailed Video Understanding
