Welcome! My name is Wenwen Xia, I’m currently a senior machine learning engineer at Ant Group. I obtained my Ph.D. degree at Shanghai Jiao Tong University (SJTU), Bachelor’s degree at Wuhan University, and was a a visiting Ph.D. student at Singapore Management Univeristy (SMU) where I worked with Prof. Yuchen Li. I also spent one year at Microsoft Research Asia (Shanghai) as a research intern. I work on graph-related learning methods (e.g., graph neural neworks), graph algorithms, large language models, and so on.

News

[2024.11] I’m move to Soochow University, Suzhou, China, as a Lecture (Assistant Professor) from Dec. 2024.

[2024.05] Our paper “Enhancing Sequential Recommendation via LLM-based Semantic Embedding Learning” was accepted by The Web conference 2024, which was held in Singapore.
