Personal Introduction

I’m now working as a research scientist in the data science lab at JD.com. Prior to that, I was a research associate in University College London, working with Prof. Ingemar Cox. I got my PhD from University of Amsterdam, supervised by Prof. Dr. Maarten de Rijke. I am interested in information retrieval, social media mining and content analysis in e-discovery. Before joining UvA, I received my B.E and M.Sc from Shandong University in 2009 and 2012 respectively, and worked as a short-term visiting scholar in Max-Planck-Institut für Informatik, 2012.
