I am a researcher at Tencent AI Lab (Jul. 2020 - present). Before this job, I obtained my Ph.D. degree in computer science from DCD Lab at Zhejiang University, and my Ph.D. advisor is Prof. Jun Xiao (Sep. 2015 - Jun. 2020). Before this, I obtained my bachelor's degree in electronic and information engineering from Dalian University of Technology (Sep. 2011 - Jun. 2015).
For my research, I am fortunate enough to have opportunities to work closely with:
• Prof. Shih-Fu Chang at Columbia University
• Dr. Wei Liu at Tencent AI Lab
• Prof. Hanwang Zhang at Nanyang Technological University
• Prof. Tat-Seng Chua at National University of Singapore
• Prof. Shih-Fu Chang at Columbia University
• Dr. Wei Liu at Tencent AI Lab
• Prof. Hanwang Zhang at Nanyang Technological University
• Prof. Tat-Seng Chua at National University of Singapore
My primary research interests are Computer Vision and Multimodal Analysis. Particularly, my current research focuses on three different levels of visual scene understanding:
1. instance-level recognition (e.g., visual recognition, detection, and segmentation);
2. scene-level recognition (e.g., scene graph generation);
3. scene-level reasoning (e.g., visual-language tasks).
