Bio

I am a faculty member at CISPA Helmholtz Center for Information Security. Previously, I was a research group leader at CISPA Helmholtz Center for Information Security. 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. My research interests lie at the intersection of privacy and machine learning. My research topics can be broadly categorized into two themes. First, I develop machine learning algorithms to quantify and mitigate privacy risks stemming from a variety of human-generated data, such as social network data, biomedical data, and location data. Second, I investigate novel attack surfaces against machine learning algorithms and develop privacy-enhancing techniques to mitigate the discovered risks. Besides, I also work on social network analysis and algorithmic fairness.
