Chenxingyu Zhao 赵宸兴宇

I am Chenxingyu (Frank) Zhao, a fifth-year Ph.D. student in Paul G. Allen School of Computer Science and Engineering at the University of Washington, advised by Professor Arvind Krishnamurthy. My research area is networking and systems, with a recent focus on evolving I/O stacks with SmartNICs for cloud and AI infrastructure. Before coming to UW, I received my B.S. in Computer Science (with honors) from Peking University, advised by Professor Tong Yang.

I have the pleasure of working with some fantastic colleagues: Jaehong Min, Ming Liu, Tapan Chugh, Tianyi Cui, Henry Schuh, and more.
