I am a Ph.D. student under the supervision of Prof. Jiawei Han at the Data Mining Research Group, UIUC. My researh interest falls in area of data management and mining, with a focus on spatiotemporal data mining and information network analysis. Prior to joining UIUC, I obtained my B.Eng. degree in 2010 and M.Eng. degree in 2013, both in Computer Science and from Zhejiang University. For more detailed personal information, please refer to my CV.
