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 to help people digest
large amount of texts efficiently, analyze information in social media,
read and write in new languages or different styles (e.g. text simplification).
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.
Sep 17 - Sep 21 2015, Lisbon for EMNLP, presenting my 2nd TACL paper Problems in Current Text Simplification Research
Oct 1 2015, speaking at the Ohio State University about "Multiple Instance Learning from Unlimited Text".

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).
