Zhihan Jiang
Ph.D. Candidate, CUHK
I am a 3rd-year CSE Ph.D. student in ARISE Lab at The Chinese University of Hong Kong, supervised by Prof. Michael R. Lyu. Previously, I obtained my Bachelor's degree from Sun Yat-sen University, in 2022.
💡 I focus on enhancing the observability and reliability of large-scale cloud systems and LLM systems, especially based on heterogeneous monitoring data (e.g., logs, traces, metrics and alerts).
My recent work explores AIOps for LLM training and serving systems (Ops4LLM) and the use of LLMs to enhance AIOps (LLM4Ops).
😃 I always welcome the opportunity to collaborate and discuss research topics. Feel free to drop me an email if you're interested in connecting with me.
