Short Bio

Currently, I am a Ph.D. candidate of Websoft Research Group at Department of Computer Science and Technology, Nanjing University. I received my B.Sc. degree in College of Computer and Information in June 2016 from Hohai University. In the same year, I was admitted to study for a M.Sc. degree in Nanjing University without entrance examination. In Sept. 2018, I started my Ph.D. degree under the supervision of Prof. Yuzhong Qu and Associate Prof. Wei Hu.


Research Interest

My research interests include knowledge graph representation learning and its applications (e.g., entity alignment, relation prediction and type inference), applied machine learning and deep learning (recurrent neural networks, multi-relational graph neural networks, etc.).
