About

Hi! I am a Research Associate at University of Cambridge, working with Prof. Andreas Vlachos. Recently, I earned my PhD in Computer Science from SUTD, under the supervision of Prof. Wei Lu. Previously, I was in ILCC at the University of Edinburgh, working with Prof. Shay Cohen, Prof. Giorgio Satta, Prof. Frank Drewes and Prof. Johanna Björklund on AMR Parsing. I also learn a lot from Dr. Zhiyang Teng.

I am most interested in structures (tree, graph, etc.) from text. How to predict the structures and apply them to different NLP tasks. Currently, I am working on automated fact-checking.
