I am a final year PhD student in Computer Science at Duke University, where I am fortunate to be advised by Prof. Danyang Zhuo and Prof. Matthew Lentz. Before that, I received my Bachelor degree from the School of the Gifted Young at University of Science and Technology of China in 2020, where I worked with Prof. Defu Lian.

My research interests include datacenter networks and machine learning systems. I build systems for high-performance and manageable machine learning training and inference in multi-tenant datacenters and cloud environments. I have also worked on data mining, recommender systems and differential privacy before.
