Hi, my name is Zhenyu Song (宋振宇, pronounced as zen-yu).

I’m currently a Ph.D. student at CS Department, Princeton, under the supervision of Prof. Kai Li and Prof. Wyatt Lloyd. I’m interested in many system topics, and currently working on using machine learning to improve content delivery network (CDN) caching.

I earned my undergrad at Shanghai Jiao Tong University. I attended Intelligent Internet of Things(IIoT), SJTU, under the supervision of Prof. Xinbing Wang and Prof. Xiaohua Tian.
