He Zhu

I am HE ZHU (朱赫), an M.Sc. student in Smart City and Data Sciences at Peking University, advised by Prof. Wenjia Zhang and Prof. Guanhua Chen. I received my B.E. in Computer Science from Southern University of Science and Technology, advised by Prof. Zipei Fan and Prof. Xuan Song.

My research centers on post-training data for LLMs: what makes it good, how to synthesize and select it at scale (FANNO, InstructDiff, Tag-Instruct, AlignDiff), and how to design training objectives that acquire capabilities efficiently without forgetting what the model already knows (ASFT, CFT). I have also applied this perspective to domain-specific foundation models for urban intelligence (PlanGPT, PlanGPT-VL, UrbanClaw). I am currently a research intern at Microsoft Research Asia, GenAI Group, supervised by Dr. Li Dong, and I serve as an Area Chair for EMNLP 2026.
