Bio

Hi, my name is Zhenyu Song (宋振宇, pronounced as zen-u). I am an Applied Scientist at AWS AI Labs, working on systems for large language models.

I obtained my Ph.D. degree from Princeton CS Department, under the supervision of Prof. Kai Li and Prof. Wyatt Lloyd, where I worked on using machine learning to improve content delivery network (CDN) caching.
