About me

I am a third-year PhD student in Computer Science at School of Interactive Computing of Georgia Institute of Technology. I am fortunate to work with my advisor Professor Wei Xu. Before that, I was a PhD student at Computer Science and Engineering department of The Ohio State University. I obtained M.S. degree in Computer Science from University of Virginia and B.S. degree from the School of Electrical and Information Engineering at Tianjin University.

I mainly work on Natural Language Processing (NLP). I am interested in semantic understanding and crowd-sourcing annotation. Previously, I also did some research on representation learning for NLP with Professor Kai-Wei Chang.

What's new?

• A long paper for monolingual word alignment is accepted at ACL2021.
• We released the complete version of Wiki-Auto dataset.
• We released the checkpoints of BERT model fine-tuned on the Newsela-Manual and Wiki-Manual datasets.
