I am currently a third-year Ph.D. student in the School of Electrical and Computer Engineering at Purdue 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 Bachelorβs 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 (2022β2023), supervised by Prof. Zheng Zhang.
π Research Interests
-
LLMs for Compilers: Exploring how Large Language Models can be leveraged to tackle long-standing challenges in Compiler Optimization. My focus is on using LLMs to improve program analysis, and automated optimization strategies, bridging the gap between human intent and efficient executable code.
-
Compiler for LLMs: Investigating LLM systems from a compilerβs perspective, with an emphasis on building efficient compilation and optimization pipelines for agentic system.
