Hi! My name is Weiwei Xu(pronunciation: /ɕy³⁵/, which is close to /ʃuː/). Now I am a 4th-year Ph.D. candidate in Computer Software and Theory at Peking University (PKU), advised by Prof. Minghui Zhou at Open Source Software Data Analytics Lab. Before that, I received my Bachelor's Degree in Software Engineering from Soochow University, mentored by Prof. Xiaofang Zhang, in 2022. From September 2025 to March 2026, I am a visiting student at UC, Davis, advised by Prof. Vladimir Filkov.

My research interests span software engineering, with a focus on open source software supply chain, open source compliance, and open source digital sociology. I am also actively exploring AI4SE and SE4AI.
