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 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.
