I am currently pursuing a Bachelor's degree in Computer Science and Technology, at School of Advanced Engineering, Shen Yuan Honors College, Beihang University.

During my junior year and prior, I conducted research on AI for Software Engineering (SE) under the supervision of Asst. Prof. Fang Liu and Prof. Li Zhang.

Currently, I am conducting my research under the guidance of Assoc. Prof. Jian Yang and Prof. Xianglong Liu, focusing on Natural Language Processing (NLP) for my upcoming Ph.D. studies. My research centers on LLM Foundation Models, including AI Infra , Data Engineering , Pre-training , and Post-training techniques for Large Language Models .
