I earned my Ph.D. degree in computer science at Zhejiang University, and my Ph.D. advisor is Prof. Jun Xiao (2015-2020). During my Ph.D., I was fortunate to have opportunities to work closely with Prof. Hanwang Zhang from Nanyang Technological University, and Prof. Shih-Fu Chang from Columbia University. Before this, I was a undergraduate student of Dalian University of Technology (2011-2015).

My primary research interests are Computer Vision and Deep Learning. 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).
