Privacy Enhancement
& Trustworthy Machine Learning

I am a second-year Master student at USTC, co-advised by Kejiang Chen and Weiming Zhang. Currently, I am a Research Assistant at Purdue University under the supervision of Ninghui Li, where I also collaborate with Yuntao Du. I used to serve as the captain of the CTF team NEBULA and worked closely with Wenliang Du, contributing to the SEED project.
