About Me

I am a staff research scientist at Google, and an incoming assistant professor of computer science at Brown University, affiliated with the visual computing group. My research interest is on computer vision and machine learning, with the focus on building machine intelligence that understands and anticipates human activities from videos, and ultimately developing autonomous machines that interact with and assist us in unconstrained environments. I am looking for highly motivated students (info for prospective students).

I work closely with Cordelia Schmid and Kevin Murphy at Google. I received my Ph.D. from the University of Southern California in 2016, advised by Prof. Ram Nevatia, and my bachelor degree in Computer Science at Tsinghua University in 2011.
