I'm now working as a professor at Shandong University. Prior to this, I worked as a senior research manager at JD.com and a research associate in University College London. 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 natural language processing. Before joining UvA, I received my B.E and M.E from Shandong University in 2009 and 2012 respectively, and worked as a short-term visiting scholar in Max-Planck-Institut für Informatik, 2012.
