Bio

I am currently a Visiting Assistant Professor at Stanford University and Research Group Leader at CISPA Helmholtz Center for Information Security. Prior to that, I was a PostDoc at CISPA supervised by Prof. Michael Backes. I obtained my Ph.D. degree from Zhejiang University, China, on Sept. 2019 (co-supervised by Prof. Jiming Chen and Prof. Shibo He). From Oct. 2017 to May 2019, I was a visiting scholar at Purdue University under the supervision of Prof. Ninghui Li.

If you are interested in working with me, please feel free to drop me an email with your CV.
