General Information

Biography (Education & Work Experience)

Victor Junqiu WEI is currently working as a research assistant professor in the Department of Computer Science and Engineering (CSE), the Hong Kong University of Science and Technology (HKUST). He obtained his bachelor degree from Nanjing University and PhD degree from Department of Computer Science and Engineering, the Hong Kong University of Science and Technology, under supervision of Prof. Raymond Chi-Wing Wong. From March 2018 to May 2018, he was a visiting student of Prof. Hanan Samet and Prof. David Mount at University of Maryland in US. He had collaborations with Prof. Raymond Chi-Wing Wong, Prof. Hanan Samet, Prof. David Mount, Prof. Pan Hui, Prof. Cheng Long, Prof. Bo Tang, Prof. Jason Chen Zhang, Prof. Haiqin Yang, Prof. Weibin Wu and Prof. Irwin King. He also has several years' working experience in the world-famous research labs in the AI industry including Baidu natural language processing (NLP) group, AI group of WeBank and Noah's Ark Lab of Huawei.

Research Statement

His research interests span spatial-temporal data management (Published in SIGMOD 2017, TKDE 2019, SIGMOD 2020, ICDE 2020, TODS 2022, SIGMOD 2023, TKDE 2024), graph data analytics (SIGMOD 2020, TKDD 2023), random sampling (ICDM 2019, ICDE 2020), AI for database management (AAAI 2021, ACL 2022, EMNLP 2022, ICSE 2023, COLING 2024, TKDE 2024). His vision is to optimize the data management and data mining applications with advanced data structures, machine learning and deep learning algorithms. He served as a program committee member of many top conferences such as ICDE, KDD, CIKM, SIGSPATIAL, ACL, NAACL, and EMNLP, etc. He has won a lot of honors and award including the best paper candidate of SIGMOD 2020.
