Biography

Tsz Nam Chan (Edison) is currently a Distinguished Professor in the database group of the Big Data Institude in Shenzhen University (SZU). He is a data engineering researcher (for handling the efficiency issues in big data settings). He published several research papers in prestigious conferences and journals (CCF: A, top ranking in Google scholar and Microsoft) in both database (data engineering) and data mining areas, including SIGMOD, VLDB, ICDE, SIGKDD, and TKDE. Prior to joining the SZU, he was a Research Assistant Professor in the Hong Kong Baptist University from Sep 2020 to Aug 2023 and a postdoctoral researcher in the The University of Hong Kong from Sep 2018 to Aug 2020. He received the PhD degree in computing and the BEng degree in electronic and information engineering from The Hong Kong Polytechnic University in 2019 and 2014, respectively. He is an IEEE senior member, an ACM member, and an AAAI member.

  • National Science Fund for Excellent Young Scientists (Overseas) (国家海外优青) (Awarded in 2023)
Recruitment

Tsz Nam Chan can recruit an assistant professor (subject to the final decision from SZU), an associate researcher (副研究员), postdoctoral researchers, postgraduate students (including master and PhD students), and software developers. If you are interested in developing efficient software packages/systems (like LIBKDV and KDV-Explorer) or complexity-reduced algorithms (like SLAM, SWS, SAFE, and PLAME) that are related to spatial/multi-dimensional databases, GIS, and statistical models, please contact me.

To all potential students: Suppose that you want to join our research group (https://szu-dbgroup.github.io/) as a PhD student/MSc student. You need to send me your CV and your transcript. Note that our research group (1) mainly focuses on algorithm development with non-trivial guarantees (e.g., time complexity reduction/accuracy guarantees) for spatiotemporal data management/graph data management, (2) aims for publishing papers in top-tier venues (e.g., SIGMOD, VLDB, ICDE, SIGKDD, TODS, VLDBJ, and TKDE), and (3) needs highly motivated students. Therefore, those students who do not fulfill the above three conditions should not join this group.

To all potential postdoctoral researchers/associate researchers: If you want to join our research group (https://szu-dbgroup.github.io/) as a postdoctoral researcher/associate researcher, you (1) must publish some papers in top-tier venues (e.g., SIGMOD, VLDB, ICDE, SIGKDD, TODS, VLDBJ, and TKDE) before as a first author and (2) must work on database/data mining/visualization/theoretical computer science areas. Those applicants who mainly want to apply machine learning models to improve the accuracy of some tasks should not apply for the postdoctoral researcher/associate researcher position in our group.

Research Interests

  • Algorithm and software development for statistical models (with non-trivial accuracy and time complexity guarantees)

  • Spatial and temporal data analysis/management (develop efficient algorithms for GIS)

  • Large-scale data visualization

  • Kernel methods, similarity measures, similarity search, and pattern matching
    		•

    Long-term Goal

    My long-term goal aims to develop the GIS (or spatial analysis), visualization, statistical, and machine learning software packages, like QGIS, ArcGIS, CrimeStat, Seaborn, Scikit-learn, Scipy, and LIBSVM, which are based on our theoretically efficient algorithms (e.g., reduce the time complexity) with non-trivial accuracy guarantees (e.g., achieve exact results or approximate results with approximation ratio). With the lower time complexity of our solutions, our software packages should be the fastest in the world.
