Yichen Li is a 4th(final)-year CSE Ph.D. student at The Chinese University of Hong Kong, under the supervision of Prof. Michael R. Lyu. Previously, He received Bachelor’s degree in Information Security from Huazhong University of Science and Technology in 2021.

My research interests include LLM for code, program analysis and AIOps. Specifically, I am devoted to improving the quality of system runtime information and utilizing system runtime behaviors for cloud incident management (Dev for Ops with LLMs).

Feel free to drop me an email if you are interested in my research or just want to talk with me 😆.
