About Me

I received my Ph.D. in the Siebel School of Computing and Data Science (Computer Science) from the University of Illinois Urbana-Champaign (UIUC), where I was advised by Dr. Gang Wang.

I have recently joined the School of Information Science and Technology (SIST) at ShanghaiTech University as an Assistant Professor in the Systems and Security Center (SSC).

My new personal website is under construction. You can reach me via email at haoqy@shanghaitech.edu.cn.

My primary research interests are security and privacy, and its intersection areas with machine learning.
