Hi, I’m Ziyi Zhou, currently a Ph.D. candidate in Computer Science and Technology at Shanghai Jiao Tong University (SJTU, 上海交通大学). Thus, if you come to Shanghai, feel free to contact me!

I come from Shenyang in the Northeast China. The Northeast China is a great place, and welcome to visit the Northeast China!!!

I’m a noob in the field of Mobile Security. Currently, I focus on finding vulnerabilities of applications and operating systems on the Android and iOS platforms, especially those that can be elevated into papers, because without sufficient papers, I won’t be able to obtain my degree🤣🚑.

I warmly welcome any opportunities for discussion and collaboration, so please don’t hesitate to get in touch with me via email at jou.dzyi@sjtu.edu.cn. I really look forward to learning from you. orz
