CISPA Helmholtz Center for Information Security


I am a PhD candidate at CISPA Helmholtz Center for Information Security, fortunately, having Nico Döttling as my supervisor. I am interested in both theoretical and applied cryptography problems, such as (post-) quantum cryptography, two-party computation, and privacy enhanced techniques.

short bio

Before joining CISPA, I worked as a software engineer in Autodesk Inc. on graphics rendering after graduating from Shanghai Jiao Tong University with Master’s degree in Computer Science, where I was supervised by Dawu Gu and Yu Yu.
