Ph.D. student and Postdoc Openings:

(1) big data analytics for online social networks using graph analytics, statistical inference and learning
(2) exploratory cloud computing and artificial intelligence using probabilistic machine learning
(3) emerging technologies for Internet of Things (IoT), e.g., Visible Light Communications
Projects (2) and (3) are in collaboration with Dr. Siu Wai Ho and Prof. Raymond Yeung. Candidates are expected to be proficient in mathematics (e.g., discrete mathematics like graph theory, linear algebra) and have good software programming experience. Please email at cheewtan @ cityu.edu.hk with CV and transcripts.
