Openings: We have openings of Post-Doc, PhD students, visiting scholars/students from time to time. Please contact me via email if you have interest.

Biography: Cheng LONG is currently an Assistant Professor at the School of Computer Science and Engineering, Nanyang Technological University, Singapore. From 2016 to 2018, he worked as an academic 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.

Research Interests: He has research interests broadly in data management and data mining. Specifically, he works in (a) spatial data management with machine learning-based techniques, (b) spatial data mining in the urban domain (e.g., traffic and mobility), (c) graph data mining (namely dense subgraph mining and graphlet mining), and recently in (d) high-dimensional vector data management (e.g., approximate neareast neighbor search). For details of his research, please refer to his research summary and publications.
