I am currently a third-year Ph.D. student in the Department of Computer Science at North Carolina State University, advised by Prof. Xipeng Shen. I also collaborate closely with Oak Ridge National Laboratory, under the supervision of Dr. M.A.H. Monil and Dr. Seyong Lee. I received my Bachelor’s degree in Computer Science and Engineering from Huazhong University of Science and Technology in 2023. During my undergraduate studies, I was an exchange student at the University of California, Santa Barbara (2022–2023), supervised by Prof. Zheng Zhang.
🎓 Research Interests
-
LLMs for Compilers: Exploring how Large Language Models can be leveraged to tackle long-standing challenges in Programming Languages and Compiler Optimization. My focus is on using LLMs to improve program analysis, code transformation, and automated optimization strategies, bridging the gap between human intent and efficient executable code.
-
Compiler for LLMs: Investigating LLM systems from a compiler’s perspective, with an emphasis on building efficient compilation and optimization pipelines for multi-agent system.
🔥 News
- 🎉 2025.04: Our paper "Reductive Analysis with Compiler-Guided Large Language Models for Input-Centric Code Optimizations" has been accepted by PLDI 2025! See you in Seoul in June!
- 🎉 2025.01: I'm glad to share that I've passed the NCSU Ph.D. written exam and have become a Ph.D. candidate!
