About me
I am a second-year Ph.D. student at Southern University of Science and Technology (SUSTech), advised by Prof. Bo Tang. I received my bachelor’s and master’s degrees from SUSTech in 2022 and 2025, respectively.
My research focuses on machine learning systems, particularly reliable LLM training and efficient LLM agent systems. I am also interested in efficient LLM inference and learning-based query optimization.
