My Curriculum Vitae

I am currently on the job market,
please contact me if there is any research related position.


I am currently a fourth year PhD student in Rensselaer Polytechnic Institute (RPI).
I am working with Professor Heng Ji at Blender Lab.
My PhD thesis topic is "Events in Social Media".

Generally, my research interests lie in Natural Language Processing (NLP) and Machine Learning (ML), especially Information Extraction (IE) and Information Retrieval (IR). 

I have conducted research on several NLP tasks including Event Extraction, Document Retrieval, Linking Tweets to News, and Sentiment Analysis, i.e., how to identify (first) important event information from news and tweets, how to bridge the gap between tweets and news, how to identify background information for tweets, how to identify user sentiment of online reviews, tweets and forums. 

I have experience to tackle various NLP tasks in different genres such as news articles, Facebook and Twitter messages, discussion forums, clinical documents and e-commerce product descriptions.
