I am a postdoc at University of Pennsylvania, working with
My research interest is centered around Natural Language
Processing, with an emphasis on data-driven approaches for
paraphrase, social media and information
extraction. I create models and systems to help people digest
large amount of texts efficiently, read and write in new languages
or different styles (e.g. text simplification for children).
I graduated with a PhD in Computer Science from New York University
and my advisor was Ralph
. My thesis work was about Data-driven Approaches
for Paraphrasing Across Language Variations
, with Bill
as committee. I received my bachelor and master degrees
in Computer Science from Tsinghua University
in Beijing, China.
April 6 2015, I will be speaking about "Learning and Generating Paraphrases from Twitter and Beyond" at Columbia University in New York. It is in the CS Conference Room (directions
), 2:30 pm on April 6.
March 27 2015, I will be speaking about "Modeling Lexically Divergent Paraphrases in Twitter (and Shakespeare!)" at The City University of New York. It is open to public at 11am, Graduate Center Room 6496 (directions

When I have spare time, I enjoy arts, traveling, snowboarding,
rock climbing, sailing and windsurfing.
I also made a list of the best
dressed NLP researchers (2014).
