Data Management @ Nanyang Tech
College of Computing and Data Science
Nanyang Technological University
Cheng Long is currently an Associate Professor at the College of Computing and Data Science (CCDS), Nanyang Technological University (NTU), Singapore. From 2016 to 2018, he was a lecturer at Queen's University Belfast, UK. He received his PhD degree from the Hong Kong University of Science and Technology, Hong Kong, in 2015, and his BEng degree from South China University of Technology, China, in 2010.
Cheng Long has research interests broadly in data management and data mining. Specifically, he works in high-dimensional vector data management (and its applications in large models such as retrieval-augmented generative AI), spatial data management with machine learning-based techniques, spatial data mining in the urban domain (e.g., traffic and mobility analysis), and graph data mining (including dense subgraph mining and graphlet mining).
