Welcome to My Homepage

I recently graduated from Data Mining and Machine Learning Laboratory of Arizona State University. My advisor is Professor Huan Liu. Before coming to ASU, I received my B.S. degree and M.S. degree in 2007 and 2010 from the School of Information Engineering, Beijing University of Posts and Telecommunications, China.
