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.
May 31 - June 5 2015, I will be in Denver for NAACL, presenting our TACL paper "Modeling Paraphrases in Twitter"
and SemEval shared task Paraphrases and
Semantic Similarity in Twitter (PIT-2015)
2015 Workshop on Noisy User-generated Text (W-NUT)
SemEval 2015 shared-task: Paraphrases and Semantic
Similarity in Twitter (PIT)

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).
