I am a faculty member at CISPA Helmholtz Center for Information Security. I sometimes also chime in iDRAMA Lab. Previously, I was a research group leader at CISPA. From January 2017 to December 2018, I was a postdoc with Michael Backes. 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.

Research Areas

  • Security and Privacy of Machine Learning
  • Social Network Analysis
  • Algorithmic Fairness

I’m always looking for motivated students to join my group. If you are interested, please write me an email (zhang@cispa.de).
