Asst Prof Long Cheng

Biography
Dr. LONG Cheng is currently an Assistant Professor at the School of Computer Science and Engineering (SCSE), Nanyang Technological University (NTU). From 2016 to 2018, he worked as a lecturer (Asst Professor) at Queen's University Belfast, UK. He got the PhD degree from the Department of Computer Science and Engineering, The Hong Kong University of Science and Technology (HKUST) in 2015.

His research interests are broadly in data management, data mining and big data analytics with his vision to achieve scalable spatial computing, to make sense of urban related data for smarter cities, and to manage and analyze emerging big data such as sports data and IoT data for richer knowledge.

The excellence of his research has been recognized with one “Best Research Award” provided by ACM-Hong Kong, one “Fulbright-RGC Research Award” provided by Research Grant Council (Hong Kong), two “PG Paper Contest Awards” provided by IEEE-HK, and one “Overseas Research Award” provided by HKUST. He has served as a Program Committee member/referee for several top data management and data mining conferences/journals (TODS, VLDBJ, TKDE, ICDM, CIKM, etc.). He is member of ACM and IEEE.

We have opennings for PostDocs, PhD students, research assistants, visting scholars/students from time to time. Please send me an email (preferably with your CV attached) if you have interests.
