About Me ([GitHub] [Google Scholar] [CV])

I am a PhD candidate at Department of Computer Science and Technology, Nanjing University (NJU). My academic supervisor is Prof. Tong Lu. I received the bachelor's degree from School of Computer Science and Engineering, Nanjing University of Science and Technology (NUST) in 2016.

I work very close with my friends Enze Xie and Xiang Li. My recent works are mainly on scene text detection/recognition, deep neural networks exploration, object detection and instance segmentation.

I am looking for a postdoctoral position or a full-time job. Please feel free to contact me through the email.
