I'm a post-doctoral research associate at the Queens College and Graduate Center, City University of New York. My main research interests widely lie in the fields of social media mining, social computing, machine learning, natural language processing, and information retrieval. My recent research has focused on the analysis of breaking news, events and trends on social media. I study how users interact and spread information in social media as news and events unfold.
New! We released a large-scale social tagging dataset, which includes almost 8 years worth of tagging data for 2 million users. Check it out!
