I am now a Tenure-track Assistant Professor (Ph.D. Supervisor) in Wangxuan Institute of Computer Technology, Peking University. Also a member of MIPL Group (led by Prof. Yuxin Peng) at Peking University.

Before joining Peking University, I was a Postdoctoral Researcher in the Visual Geometry Group (VGG) at University of Oxford, supervised by Prof. Andrew Zisserman. I received PhD and MPhil in Advanced Computer Science from University of Cambridge, and B.Eng. in Telecommunication Engineering from Beijing University of Posts and Telecommunications (BUPT).

My research interests include computer vision, natural language processing and machine learning, with an emphasis on how these areas can collaborate best to perform real-world tasks. Below are some of my recent research topic:

  • Intersection of visual and language (Retrieval, Captioning, Visual grounding, Visual question answering)
  • Image and video semantic analysis (Image and vieo Classification, Detection, Segmentation)
  • Machine Learning (Deep learning, Multi modal Learning, Transfer Learning, Self supervised learning)

We are always actively recruiting postdocs, Prospective graduate students and interns!

Welcome to contact me with your detailed CV! Please read this Note first!
