Biography

I am an Associate Professor at the School of Computer Science and Software Engineering, East China Normal University, since Sept 2014. I’m interested in many interesting topics around web data mining and large scale big data systems. My research focuses on innovative problem solving and attractive scenarios.

Before joining ECNU, I spent one year at the American Riviera town, University of California, Santa Barbara as a post doc visitor. I get my Ph.D from Peking University in 2013.
