About Me
I am a 3rd-year PhD student in the Computer Science Department (CSD) at Carnegie Mellon University (CMU). I am fortunate to be advised by Prof. Justine Sherry and work with Prof. Arvind Krishnamurthy and Vincent Liu. My research interests include GPU communication efficiency and programmable networks. Prior to CMU, I earned BS and MS degree at Tsinghua University and was advised by Prof. Mingwei Xu.
