I am a research group leader at CISPA Helmholtz Center for Information Security, Saarland Informatics Campus.

My research mainly concentrates on privacy in the modern society. Topics include machine learning privacy, biomedical privacy, social network privacy, and location privacy. Besides, I also work on urban informatics/computing, social media analysis, and data mining.

From January 2017 to December 2018, I was a postdoc with Michael Backes at CISPA. Prior to that, I obtained my Ph.D. degree from University of Luxembourg on November 2016 under the supervision of Sjouke Mauw and Jun Pang. I obtained my bachelor (2009) and master (2012) degrees from Shandong University, China.
