Introduction

Welcome to The Knowledge Computing Lab (KCL) of Peking University, a center of excellence for knowledge computing research and practice established in 2017.

The Knowledge Computing Lab at Peking University is part of National Engineering and Research Center for Software Engineering, where faculties, students and software engineers work together on advanced algorithms towards natural language understanding and programming language comprehension. Our research topics are centered on large language models (LLMs), including but not limited to LLM pre-training and fine-tuning, Code LLM, multi-modal LLM, LLM evaluation, and LLM applications. We have won more than 10 awards in national and international AI competitions. We distinguish ourselves as being practice-oriented, as our researches have been applied in large-scale real-world projects in areas such as enterprise intelligence, medical AI, petition, legal system, and human resources.

The National Engineering Research Center for Software Engineering was established in July 1996. Professor YANG Fuqing, Academician of the Chinese Academy of Sciences, served as the founding director. As a national research institution, the center focuses on technological innovation and has successfully built SDKs and supporting tools for industrial software development and production. It has established itself as a pioneer in many emerging but strategic areas such as government big data, software and system security, human-machine integration, intelligent sensing computing, smart cities, and blockchain.

We are looking for highly self-motivated students to work with us as PhD candidates (several positions open for 2025 Fall) or for Master's Degree. If you share our vision and are interested in working with us, please send your resume to wye#pku.edu.cn.
