About

I am currently a Senior Researcher at Microsoft M365 Research Group. Before joining Microsoft, I received my Ph.D. degree from Tsinghua University in 2021, under the supervision of Prof. Dan Pei in the Netman Group. My research spans Software Engineering, Systems, and Artificial Intelligence. My research interests are primarily focused on AI for IT Operations (AIOps) / Cloud Intelligence.

I am enthusiastic about making contributions to the AIOps ecosystem to facilitate collaboration between industry and academia. Together with Prof. Dan Pei, we launched the 4th CCF AIOps Challenge and Workshop from November 2020 to May 2021. Our team has released AIOps tools and benchmarks for multiple AIOps scenarios.

🆕 Our team has released AIOpsLab, an open-source framework designed to evaluate, improve, and standardize AI agents for automating cloud operations. It provides a reproducible environment for realistic service operations, allowing researchers and engineers to enhance agent performance and capabilities with improved observability.

I always seek self-motivated undergraduate, master's, and Ph.D. intern students with strong programming skills. Please email me your CV if you are interested in working with me.
