About Me

I am a post-doctoral researcher in the Data Mining Group at the University of Illinois, Urbana-Champaign (since January 2013), working with Professor Jiawei Han. I received my Ph.D. in Computer Science in Summer 2012 from the University of Maryland, College Park, working with Prof. Jimmy Lin.

My research interests are data mining, large-scale data analytics, information retrieval, and machine learning, with a focus on efficient, scalable, and robust techniques for mining and search large-scale structured data (e.g., information networks and social networks), and unstructured data (e.g., text data from the Web and social media). I work with researchers from diverse domains to advance state-of-the-art mining and retrieval techniques for large-scale datasets. I have a Master's degree from the Computer Science Department, University of Wisconsin, Madison, and a Bachelor's degree from the Computer Science and Engineering Department, University of Florida.
