I am currently working as theortical researcher at Theory Lab, Central Research Institute, 2012 Labs, Huawei Technologies Co., Ltd.. I got my Ph.D. degree of computational mathematics in June, 2020, at Peking University, China. My supervisor is Prof. Sihong Shao.

Research interests

My major research interest is about graph algorithm, graph data mining, and vector database.

What’s new

Recently, our team’s approximate nearest neighbor search method qsg-ngt acheived the best performance on ANN-Benchmark (https://ann-benchmarks.com/).

We propose PR-GPT (Pre-trained & Refined Graph ParTitioning) based on a novel pre-training & refinement paradigm, which won the streaming graph partition track championship on graph challenge organized by MIT.
