Biography
I joined the Chinese University of Hong Kong (CUHK) as an Assistant Professor in Dec 2018. I received my B.E. in Software Engineering in 2011 from Fudan University and PhD in Computer Science in 2016 from Nanyang Technological University, Singapore. Before joining CUHK, I spent one and a half years at the University of Queensland, Australia as a research fellow.
Research Interest
Database and data mining, with a special interest in big data processing and analytics. Current topics include:
-
Sampling-based approximation algorithm design;
