About Me
I am a research assistant working with Prof. Chang Lou of LiftLab at University of Virginia. Fortunately, I am also advised by Dr. Zhen Zhang, Johns Hopkins University, Dr. Yuan Zhou, Cornell University, and Dr. Shaowei Zhu, Princeton University.
My research interests are primarily on improving the reliability and efficiency of distributed systems. One focus is to detect and localize silent errors in real-world cloud and ML systems.
For the past year, I’ve working in providing reliability support for machine learning developers, inspired by observations made from our collaborating team in AWS.
From 2021 to 2023, I worked at Alibaba Group as a full-time software engineer in Guangzhou, China, undertaking objectives of enhancing quality and efficiency while empowering internal teams.
