About Me (CV)

I'm graduating in 2026 and actively seeking full-time opportunities. Please check out my CV and feel free to contact me if you're interested!

My name is Zheng Yu. I am a PhD candidate in the Computer Science department at Northwestern University, advised by Prof. Xinyu Xing. My research interests include System Security and AI Security. My goal is to enhance the security of programs with minimal human intervention.


I obtained my bachelor's degree from the ACM Honor Class at Shanghai Jiao Tong University, majoring in Computer Science. My advisor was Prof. Chao Li. Additionally, I was also very fortunate to be advised by Prof. Meng Xu at the University of Waterloo during my research visits.


Besides, I am very interested in and good at algorithm design. I was an OIer when I was studying at Yali. I am also a CTF player; I used to play CTF with Nu1L and StrawHat.


Outside of research, I enjoy traveling and painting, including watercolor and sketching. Here is a gallery that is still under construction.
